I am 55, weigh 135lbs, and have had HepC for 35yrs or so. I have a black spot on one tonsil, no sore throat, but have had a sinus infection and blood/mucus drainage on that side for several months now. It started with not taking care of the upper back tooth. I ve been through 14 days of antibiotics but I still have it. Any thoughts on some of these things?
