Since 1+ month I am getting this side of joint pain. Its not pain as normal type when i push something with my finger it feels burning and achy. Only that area which is encircled. Please help me :(. Is this arthritis? I am 26 and I don't drink or smoke.. that area is also looking darkened. Cbc: Normal Sugar: Normal Uric acid: done a few months back it was around 6.7 I don't eat non-vegetarian much. No diabetes. Also the pain is not there while doing any heavy activities, but when i try to pop my joints its achy/burning type pain. And it's there obly on the left side arm finger joint, right side is absolutely fine. And joints has no black skin on them on right side too.
