Last week I noticed I had this whitish colored "lump" on the right side of my throat, on my tonsil. I decided to get it checked out by a doc, who said it was an abscess, prescribed Levequin and sent me on my merry way. He was amazed by the fact that I was in no pain, none whatsoever. The area around the "lump" is red, so he just assumed I was hurting, but I have no pain when swallowing, eating, etc. I have been on the Levaquin 4 days now, tomorrow is the last day on the antibiotic, and there has been no change to the "lump". I am wondering if anyone else has had this? What was needed to get rid of it? The only symptom I have from this, is a foul taste in my mouth occasionally when I swallow. It reminds me of the taste in your mouth when you have strept throat. What caused this? Should I be concerned??
