Hi there. I have a lump on my right tonsil that is grey in colour with a black centre. It started off a few months ago as a white lump behind the tonsil tissue . I do suffer from tonsilithes but this time I have no bad taste in my mouth. When I swab the lump however with a cotton bud, it is a bit smelly. I have been on a course of antibiotics for the last week but no improvement. My GP has no idea what it is nor has he referred me. I m worried, he is not. Although he admits he has never seen anything like it before! Please help..
