41F I’ve had osteoarthritis for 10+yrs. My symptoms have always been more aligned with an inflammatory arthritis, but I’ve tested negative for RA. 2-3wks ago I got a rash on both elbows suddenly. At the same time my elbows, especially my left began aching kind of like tennis elbow. I think this may resemble psoriasis. Then it hit me, I may have had psoriatic arthritis all this time. Does this look like psoriasis? Should I get a rheumatologist appointment?
