I have had strep throat too many times to count but about 5 years ago I had the worst strep infection yet (throat so swollen that I was having difficulty breathing and took 3 types of antibiotics to get rid of...) after that infection I was referred to a specialist to follow the infections to see if my tonsils should be removed (b/c of repetitive infections) however they just said if I had one more infection they would remove but since then I have not had any. It is so weird b/c since I was young I had 2-5 strep ouinfections a year but since that last crazy infection - NONE! Also about a month or so after the last infection I noticed somewhat of a whitish/grey spot (about a 1/2 inch in size) on my right tonsil, not concerned I just thought it was maybe scar tissue or something. Recently, I noticed the whitish area has turned a purplish/black color. Any thoughts? I have a history of smoking - should I be worried or no. There is no pain surrounding the area, just an abnormal color.
