I am feeling lumps under my skin from some days. Its showing under my knee’s skin and is quite firm. It pains sometimes but I have learned that it does not pain in most of the cases. I wish to know about the causes of this Rheumatoid Nodules so that I could take care in future. What are the different treatments by which it could get fixed? Is there any difference between Rheumatoid Nodules and Rheumatoid Arthritis?
