I have been really sick for two months. Severe sore throat my doctor says is chronic Tonsilitis, lots of coughing, and today I developed fever blisters in and on my mouth and had a severe pounding headache. I am taking amoxicillin 500mg twice a day for 30 days. What is this awful stuff and will it be another two months before I feel better? I've also lost 11 pounds in these last two months of being sick. The doctor says we may need to look at removing my tonsils, but I've heard horror stories about doing this at my age, I am 45.
