I am currently having extreme burning and itching under the skin, along with deep pain seemingly in the joint or bone. There is no rash or hives. It is under the skin in the tissue and it's been going on for over a month now. I have it in my feet, toes, hands, fingers and sometimes knees. It is the worst in the late afternoon/evening. The area swells up and is red when affected. I am concerned because my father had both MS and Rheumatoid Arthritis. I don't know if it's applicable, but I've recently started running, and the symptoms started a few days after my last race.
