I have a small bruise with a hard white center that is tender to the touch on my arm located halfway between wrist and elbow. I noticed it 4-5 days ago and there hasnt been much change. There dosent seem to be any bite marks.  What could this be? Should I see a doctor?
Hi, From history it seems that there might be having something poisonous bite or some ingrown hair follicle infection giving this problem. Go for one antibiotic medicine course like Amoxicillin for 3-5 days. Ok and take care.
