Hi I m 21 years old, my height is 5 ft 6, weight is about 9 stone, my question is, I had sex bout 3 month ago, about 2 weeks after I started getting red tiny spots in my mouth, there not painful and do not bleed, I can feel them with my Tongue, there near the back of my mouth not far away from my tonsils, there in the exact same place on each side, cant see them in the mirror, and just a couple of days ago my knee starting aching and my left hand what could this be?
