Nodules are rare as well, but can develop anywhere on the body
There are a few other skin conditions that are also related to rheumatoid arthritis. Like RA rash, only a percentage of those with RA will experience these skin conditions.
Nodules are when hard lumps form right under the skin. Their sizes can vary drastically, and it is noted that some can be the size of a pea, while others could be as large as a golf ball. They can develop almost anywhere, regardless of whether the area of the body is bony or fleshy.
