What Is Psoriatic Arthritis
Psoriasis is a skin condition that is similar to eczema, but they have slight differences. Psoriasis generally has all the itchiness factor, but most people report it also feels like a sting or burn. Frequently, patients that have psoriasis will develop arthritis which is a condition called psoriatic arthritis.
Psoriasis or red patches of skin covered with silvery scales will appear first. Later, the stiffness, swelling, and joint pain will emerge. The final diagnosis is psoriatic arthritis which there is currently no cure for. The condition is chronic, and it will get worse as the years go by. Patients will experience times when the symptoms are worse and then periods of remission.
The symptoms and signs are very similar to someone who has rheumatoid arthritis, especially if they are suffering from eczema or other skin conditions at the same time. Only a medical doctor can determine whether youre experiencing rashes from rheumatoid arthritis, so that an effective treatment plan can be put into place.
Stage : Symptoms Are Visible
In this latter, more severe stage, blood tests and imaging are less relevant for diagnosis because you can actually see the effects of the disease. The joints start becoming bent and deformed, the fingers become crooked, Dr. Bhatt says. These misshapen joints can press on the nerves and can cause nerve pain as well, he says. In the older days we used to see more deformed joints when we did not have much treatment, but now we are seeing less and less, Dr. Bhatt says.
Skin Rashes Or Open Sores
Visible changes to the skin are occasionally associated with rheumatoid arthritis. Rashes and open sores may be painful, itchy, or burning. While these skin abnormalities frequently develop on the lower legs, they can appear anywhere on the body.
Rashes and sores that may be associated with RA can vary widely in appearance. Examples include the following:
- Rheumatoid small-cell vasculitis10,11 can cause a rash of dark red or purple bumps on the skin. The bumps may form lesions and scab over.
- Urticarial vasculitis10 causes hives or raised pink patches. The patches may have whitish centers. On darker skin, changes in skin color may be less noticeable, but the skin will still be raised.
- Panniculitis10 refers to a family of conditions that cause painful red or purple lumps to develop on the lower legs. The most common type of panniculitis, erythema nodosum, may look like multiple bruises on the shins.
- Pyoderma gangrenosum10 typically begins as small red bumps that expand into painful open sores, sometimes in a matter of days. This condition is very rare and typically affects the skin on the lower legs.
- Infections may cause red or pink skin and eruptions that look like blisters or pimples. The affected area may ooze fluid or be crusted over.

What Causes Arthritis Of The Knee
Experts have identified some genes that might cause arthritis, including arthritis of the knee. They predict that there are more genes not yet discovered. You could have a gene linked to arthritis without knowing it and a virus or injury could trigger arthritis of the knee.
Though the cause is unknown, some risk factors increase the possibility of arthritis of the knee. Risk factors of osteoarthritis, specifically, include:
- Age. Osteoarthritis happens to older adults more often than younger adults and children.
- Bone anomalies. Youre at a higher risk for osteoarthritis if your bones or joints are naturally crooked.
- Gout. Gout, also a type of inflammatory arthritis, might lead to osteoarthritis.
- Injuries. Knee injuries can cause arthritis of the knee.
- Stress. A lot of stress on your knees from jogging, playing sports or working an active job can lead to osteoarthritis of the knee.
- Weight. Extra weight puts more pressure on your knees.
What Causes A Rash In Rheumatoid Arthritis
Eczema, Sweet’s syndrome, and pyoderma gangrenosum are all related to autoimmune problems. Both Sweets syndrome and pyoderma gangrenosum are neutrophilic dermatoses, inflammatory skin conditions related to an overload of a type of white blood cell called neutrophils. Neutrophils naturally produce an inflammatory response to infection. In an autoimmune condition, the skin may be attacked as foreign by the immune system, leading to neutrophils overwhelming the skin and causing inflammation as if the skin was infected.
While the precise cause of eczema is not known, it is generally considered to be an autoimmune response that causes inflammation of the skin. Other autoimmune conditions besides RA have been associated with eczema, including Crohns disease and ulcerative colitis.
Rheumatoid vasculitis is caused by inflammation of both small- and medium-sized blood vessels, often as part of an RA flare-up. It usually occurs in people who have had severe RA for more than 10 years. Certain factors play a part in those who are at higher risk for this complication. Most people who develop rheumatoid vasculitis have a high rheumatoid factor in their blood and many smoke cigarettes.
Palmar erythema, reddening in the palms, has a wide variety of causes. When someone with RA experiences red palms, however, it is most likely to be as a result of an autoimmune response. It can also be caused by medication taken to treat RA.

Itching Or Burning And Joint Pain
- Medical Author: Dan Brennan, MD
Reviewed on 6/15/2020
Your symptoms can be caused by multiple medical conditions, including rheumatologic and other medical conditions. If you are concerned about your symptoms, you should contact your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Other Types Of Arthritis
Another less common type of arthritis is called gout. Gout occurs due to a high uric acid concentration in your blood, which forms sharp urate crystals in your joints. These crystals cause the intense sensations of pain, swelling, and tenderness characteristic of a gout attack. These attacks are frequently sudden and often occur in the big toe.
There are also many other types of arthritis. Additional types with a brief description are listed below:

How Seasonal Allergies Impact Chronic Illness
Seasonal allergies are uncomfortable and can cause or aggravate other health problems.
When my seasonal allergies strike in the Spring, I feel it in my joints and in my gut, says patient advocate Zoe Rothblatt, who lives with spondyloarthritis and Crohns disease. Along with the sniffles and congestion headache, my joints get a fiery ache and I get a crampy ache in my gut.
When To See A Healthcare Provider
Anyone experiencing symptoms of joint swelling, pain or tenderness, particularly worse in the morning, and/or fatigue for several weeks, should be evaluated by a healthcare provider.
A rheumatologist is a specialist who diagnoses and treats RA and other autoimmune illnesses. While primarily targeting the joints, RA can lead to inflammation elsewhere in the body, including of the heart or lungs, so untreated disease can lead to serious complications and long-term disability.

Rheumatoid Arthritis And Skin Vasculitis
Rheumatoid arthritis can also cause inflammation of the blood vessels, known as vasculitis. Most often, small blood vessels are involved, notably those that supply blood to the skin on the fingertips. This usually looks like a blue or purplish rash near the fingernails, Dr. Tehrani says.
More serious forms of vasculitis can occur in larger blood vessels, such as those in the legs, and cause painful rashes or ulcers. If left untreated, these ulcers can become infected, so see a doctor immediately if you suspect an issue.

How Is Rheumatoid Arthritis Treated
There is no cure for rheumatoid arthritis. But there are treatment options your doctor can prescribe to help manage your pain and stop further damage to your joints. Your doctor may recommend a combination of medicines, including:
- Pain relief medicines, such as paracetamol.
- Omega-3 supplements. This is a type of fat naturally found in foods such as certain fish that you can take as a food supplement to help with pain and stiffness.
- Non-steroidal anti-inflammatory drugs or cyclo-oxygenase-2 selective inhibitors. These are pain relief medicines that your doctor might prescribe when paracetamol and supplements do not relieve your pain and stiffness.
- Disease modifying antirheumatic drugs , such as methotrexate. These are a group of medicines that reduce your symptoms and the damage to your joints, including medicines known as biologic DMARDS .
- Corticosteroids, such as prednisolone. These are medicines that can help manage your pain and stiffness during flare ups. Corticosteroids are available as tablets, or it might be injected by your doctor into a joint to reduce pain.
Other complementary treatments such as massage, acupuncture or transcutaneous electrical nerve stimulation can help reduce your pain. But they will not reduce the damage to your joints and should not replace your prescribed medications.
Tripterygium wilfordii is a Chinese herb that is not recommended to treat rheumatoid arthritis as it can have dangerous side effects.

Ra’s Effect On The Brain
Learn about the possible links between rheumatoid arthritis and cognitive effects and how to manage them.
A lot of people with rheumatoid arthritis report having trouble with memory, attention, and mental focus. They forget names and appointments, struggle to find the right words and have trouble making and carrying out plans. Some say that the loss of mental clarity, commonly called brain fog, is almost as distressing as arthritis itself.
Limited Research
Its hard to say exactly how common fuzzy thinking is in RA because researchers have largely ignored it.
We have relatively good literature on cognitive problems in lupus and fibromyalgia, where brain fog is well established, but nobody has really studied RA, explains Patti Katz, PhD, a professor of medicine at the University of California, San Francisco.
Katz and her colleagues looked at 15 studies on RA and cognition published between 1994 and 2016. Many were small less than 100 patients and not all were high quality. Yet most showed that people with rheumatoid arthritis performed more poorly on cognitive tests than their peers or controls. Memory, verbal communication, attention, concentration and problem-solving seemed to cause the most trouble.
Who Gets It and Why?
There are several theories why cognitive problems may be more common in RA and other inflammatory types of arthritis.
But Katz thinks it might not be that simple.
Some factors that may contribute to brain fog include:
What the CDC Says
The Preclinical Phase Of Ra Development
Multiple studies now demonstrate that there is a preclinical phase of RA development during which there are abnormalities of autoantibodies and inflammatory markers prior to the onset of appearance of the signs and symptoms of joint disease that characterize clinically apparent RA . Some of these studies have been prospectively conducted however, most have utilized biospecimens fortuitously collected prior to the onset of RA. As such, the exact timing of appearance of biomarkers prior to the onset of signs and symptoms of RA has been difficult to identify, but overall RA-related biomarkers, and especially autoantibodies, seem to appear in the circulation on average 35 years prior to the onset of clinically apparent RA.

Rheumatoid Factor And Anti
One blood test measures levels of rheumatoid factors in the blood. Rheumatoid factors are proteins that the immune system produces when it attacks health tissue.
About half of all people with rheumatoid arthritis have high levels of rheumatoid factors in their blood when the disease starts, but about 1 in 20 people without rheumatoid arthritis also test positive.
A related blood test known as anti-cyclic citrullinated peptide test is also available. Anti-CCPs are antibodies also produced by the immune system.
People who test positive for anti-CCP are very likely to develop rheumatoid arthritis, but not everybody with rheumatoid arthritis has this antibody.
Those who test positive for both rheumatoid factor and anti-CCP may be more likely to have severe rheumatoid arthritis requiring higher levels of treatment.

What Is Dermatomyositis
Dermatomyositis is a rare disease that causes muscle inflammation and skin rash. Its one of a group of muscle diseases that cause muscle inflammation and swelling. It’s different from other muscle diseases because it also causes skin problems. Dermatoyositis is the term used to describe both muscle and skin symptoms.
It can occur at any age, but it most often affects adults ages 50 to 70. Women are twice as likely as men to be diagnosed with the disease. Some people with the disease also have a connective tissue disorder, such as lupus or rheumatoid arthritis.

What Actually Is Hives
Also called as urticaria, it is a skin reaction that leads to itchy nettle rash. It can range in size from tinny spots to large blotches as large as your hand . It may appear suddenly on a small area of the skin or affect across large areas, depending on the severity of the problem.
The symptoms of itchy nettle rash associated with hives include:
The risk factors, conditions /factors that increase your risk of developing hives, are as follows:
Hives is common, and having some of risk factors mentioned above can put you at higher risk than others.
It can be acute or chronic. Acute or short-term hives can affect about 1 out of 5 people at some point in their lives. Chronic or long-term hives is less common, but it is more difficult to treat.
Causes
Some people have hives when a trigger leads to high levels of histamine and other certain chemicals in the skin.
Who Will Be Responsible For My Healthcare
Youre likely to see a team of healthcare professionals.
Your doctor, usually a rheumatologist, will be responsible for your overall care. And a specialist nurse may help monitor your condition and treatments. A skin specialist called a dermatologist may be responsible for the treatment of your psoriasis.
You may also see:
- a physiotherapist, who can advise on exercises to help maintain your mobility
- an occupational therapist, who can help you protect your joints, for example, by using splints for the wrist or knee braces. You may be advised to change the way you do some tasks to reduce the strain on your joints.
- a podiatrist, who can assess your footcare needs and offer advice on special insoles and good supportive footwear.

How Is Rash From Rheumatoid Arthritis Treated
Depending on the type of rash, treatment options may vary. Palmar erythema may not be treated at all if it is not causing distress. If the reddening of the palms is caused by a drug, your doctor may recommend stopping that medication.
Rheumatoid vasculitis is usually treated by management of the underlying RA. If the vasculitis is confined to the fingertips and skin around them, antibiotic cream along with pain control is often prescribed. Rheumatoid vasculitis symptoms indicate that your current RA treatment is not working well. It is important to contact your doctor if you have symptoms of rheumatoid vasculitis.
Minor cases of eczema may be treated with topical ointments. More severe cases are treated with immunosuppressant drugs and biologics, including some disease-modifying antirheumatic drugs that are also used to treat rheumatoid arthritis.
Sweet’s syndrome is often treated with oral corticosteroids. The symptoms often go away after a few days of treatment, but to prevent the rash from coming back, steroids are usually taken for several weeks or months afterward. Topical corticosteroids may also be used in some cases.
Pyoderma gangrenosum has a variety of treatments depending on how advanced the rash is. In earlier phases, topical corticosteroid ointments are usually combined with oral anti-inflammatory antibiotics, like doxycycline or Dynacin . Larger ulcers are treated with steroids like prednisone and, in severe cases, surgery to remove the affected skin.
