I have a small dark grey to black spot on the inside of my cheek. there is also some white patches or really look like a line of white film on the cheek. I have had a like tonsil infection (but have had my tonsils taken out when young ) this is been since April and have also about a month later had to have a place lanced in the same right toward back of throat from an abcess and have taken lots of meds for this. Then week and a half ago had a basil cell skin cancer removed from my left nostril and a skin graft from left ear with a z pack. I just noticed this spot like in the last couple of days. And I take methrotrate for LYP
