Hello. I m Dr. Christensen. I m sorry you don t feel well. It isn t possible to diagnose your condition without a thorough evaluation, but the spots on your legs might be a condition called erythema nodosum. This is an inflammatory disorder that affects the fatty tissues beneath the skin surface, and it can be seen in a number of situations: Strep infections, catch scratch fever, infectious mononucleosis, inflammatory bowel diseases, sarcoidosis and medication reactions are only a few of the conditions that have been linked to erythema nodosum. Many of these disorders could account for your other symptoms, too. I suggest you see your primary care physician at your earliest convenience. He/she will want to perform a physical examination to look for other clues to your underlying diagnosis, and I suspect you ll need some blood tests, as well. I hope that answers your question. Good luck!
