Arthritic nodules are caused by inflamed joints. Usually, if you have it in one hand you will have it in both. It is most common in the wrist and knuckles. According to Pub Med Central, there are very few treatment options for rheumatoid arthritic nodules. Occasionally the nodules go away by themselves. Assh.org says, surgical interventions may be needed to maximise function and minimise deformity, which may include removing nodules that are putting pressure on the joints and tendons. (Reference 2) There are other options you can also try to remove arthritic nodules from your hands.
Talk with your doctor about prescription medications, both oral and gels, to treat arthritic nodules.
Injections of steroids can reduce the size of the nodules and bring relief in some cases.
Therapy can help. Some people have had help from soaking or exercising hands in warm water, having splints applied or hot and cold soaks. These therapies not only make it feel better but will help inflammation and muscle spasms.
Eat right. Oleic acid, a omega fatty acid, will help because it helps keep inflammation down. You will find it in olive oil, fish, nuts, fruits, garlic, herbs, chocolate and tea.
Take vitamin D supplements. According to Pub Med.gov, a greater intake of vitamin D may be associated with a lower risk of rheumatoid arthritis.
See your doctor for the best treatment for you.
