Question: I was diagnosed 2 weeks ago with tendonitis of my right wrist, although my rheumatologist said it could also be a ganglion cyst too since I have a small bump on the volar side of my wrist just below the wrist joint. I have a history of osteoarthritis and I have had pain in this right wrist for 2-3 years as well as some joint pain their also but the small bump just showed up recently. The swelling on my wrist comes and goes and gets worse with overuse or repetitive motion. Just today I noticed a slightly swollen area on my right inside upper forearm and when I felt the area, there seems to be a soft small painless lump under the skin. I did not notice this lump before I was diagnosed with tendonitis. Even though the lump is painless, I have some discomfort of the area when doing certain activities such as, typing at the computer, holding my arms in the same postion when driving, and carrying heavy grocery bags. Here are my questions:
1. Can tendonitis of the wrist or a ganglion cyst cause this type of problem in the forearm?
2. Is this really a lump of some kind or could it be a larger muscle or tendon? I am right hand dominant and that arm is slightly bigger than my left anyway.
3. I have heard about soft tissue sarcomas, and I am very scared. Could this be the problem?
I not only get pain in the wrist area, but also the thumb. When my wrist and thumb are hurting, sometimes the forearm will hurt too. Please advise. I am very concerned.
