The problem I have been having , several times over the last year and 1/2, I developed a really bad sore throat, for no reason.

I look in my throat and on both sides it looks bumpy? I have seen white bumps in the past but not this time. I use salt water and the doctor gave me antibioits, two weeks ago. It is still bumpy and I do have a sore throat. No fever that I know of. I have had a post nasal drip. Would that cause cronic tonsillititis?Should I have them taken out. I had a Anterior cervical discectomy and fusion in Aug.08, and since have devoloped thyroid diease, and I would this problem with my sore throat thing. Any help/suggestion would be great. Thank you for your time and I look forward to hearing from you soon.
