If you have RA, your immune system becomes overactive and attacks healthy parts of your body. This leads to inflammation, as well changes like yellowing, thickening, or vertical lines on your nails.
Rheumatoid arthritis (RA) is a chronic autoimmune condition that can affect your:
- energy level
Changes to your nails can be signs of RA or other systemic conditions and should be diagnosed by a doctor.
Most nail changes from RA do not need to be treated independently from the condition. RA can be managed with medication, and treatment may improve changes to your nails.
If left untreated, RA can damage your joints and the bones that surround them permanently.
Changes to your nails may be a symptom of RA or another condition.
Nail changes related to RA are generally not painful and do not require specialized treatment.
Longitudinal ridging, or onychorrhexis, is when your nails have lines that run parallel from the bottom to the top of the nail. These lines create subtle or deep grooves along the nail.
You may seek treatments beyond RA management for the ridging to protect your nails, though nail ridging alone is not treated with a topical. What you can do at home is take care of your nails by applying moisturizers, avoiding exposure to harsh chemicals, and practicing nail hygiene by keeping your nails trimmed and clean.
Yellow nail syndrome
Yellow nail syndrome occurs when your nails become thicker and yellow in color. The white half-moon shapes at the bottom of your nail may disappear. The sides of the nail may begin to curve.
This condition can occur if you have RA. According to the National Organization of Rare Disorders, research suggests it might occur due to certain medications used to treat RA, but further studies are needed. Ask your doctor or a dermatologist for treatment options to try that are right for your specific situation.
Red streaks or lines under your nails might be the sign of splinter hemorrhages. Capillaries leaking under the nail cause these lines. You could develop these from RA, but nail trauma, nail fungus, and health conditions like endocarditis can also be causes.
Splinter hemorrhages may disappear with time or grow out with your nail. RA treatment may take care of recurring splinter hemorrhages.
This condition occurs when your nail lifts from the finger bed and leaves a white mark under the nail. You might experience this with RA, but onycholysis is mostly associated with psoriatic arthritis.
There is a chance your nails may experience clubbing from RA if your lungs are affected. Clubbing occurs when your nails begin to curve downward as they grow. This creates swelling in your fingers. Your nails may feel like a sponge.
This condition affects your nail beds and not your nails themselves. It happens when blood vessels dilate and are visible near the skin’s surface. It may be referred to as spider veins. It can also occur with other autoimmune conditions like lupus and scleroderma.
There are treatments for spider veins, such as laser therapy and surgery, but you should also seek treatment for the underlying condition if you experience spider veins at the bottom of your nails.
Here are some images of nail changes associated with RA.
Nail changes in RA are not detrimental to your quality of life, unlike some nail changes caused by psoriatic arthritis. Psoriatic arthritis is an autoimmune condition that affects the skin and joints and can cause nail lesions. According to one study, up to
Psoriatic arthritis can also cause nail conditions including longitudinal ridges, splinter hemorrhages, and pitting.
Changes to the nails could be a symptom of RA, but there are other more severe RA symptoms that impact your overall health, including:
- swollen, tender, red, and stiff joints on one or both sides of your body
- slight fever
- weight loss
- shortness of breath
You may experience worsening symptoms with untreated RA or when you experience a flare.
Your doctor will recommend a treatment plan to manage your RA, which may address the nail changes if they are caused by overactivity of your immune system. If you have noticeable nail changes that do not respond to your RA medications, talk with your doctor about other treatment options.
RA treatments vary from person to person. Some medications used to treat RA include:
