It sure sounds to me like you need a powerful antibiotic. It sounds like you have an infection, and it needs controlling before it REALLY gets out of control more than it already has!!!
I would definitely TELL my doc I WANT an antibiotic. I wouldn't ASK for it, I'd TELL him that I WANT one. And he'd better give it to you because from the sounds of it, that's what's going on. I would bet that after 10 days of treatment, you'll be feeling much better, as long as he gives you a strong enough antibiotic.
I wish you the very best. Let us know what happens, will you?? God bless and please take care. Hugs, Lee
