I have had pain in my upper arm for 3 months now. In early February I had a cellulitis flare up. I had an MRI which showed a small mass and an ultrasound showed it was fluid filled. My doctor and the surgeon both told me this was not consistent with any type of cancer.
The anti-inflammatory meds that I’ve taken really don’t seem to help. It’s a dull achy pain from my shoulder to my elbow but seems to “burn” or ache in my upper arm. They are now saying it could be tendonitis. I’m in the dental field and use my arm alot. What does this sound like to you?
