Well, here I am again asking questions! I have been really sick for about a week now. I've been blaming the ragweed (it's horrible here from mid-August to 1st frost usually in November) but I think my right sinus is infected again. I spent 18 years straight on every antibiotic I think that was ever made! After I started the abx last October I haven't had a sinus infection. I am still on everything but what if I add a rocephin shot to the mix? My gp might give me one or two. I've had to have endoscopic cultures done of my right sinus for years. Otherwise, it's like a shot in the dark trying to kill an infection. I've probably got lots of mutated bugs from all the years of one antibiotic after another. I'm sure if I went to an ent doc (ear, nose,throat) he wouldn't put me on another antibiotic with what I'm already on. Maybe I can just call my doc (that put me on the protocol) and see what he says. It's still going to be guesswork though. I am really discouraged now. I really thought I had beaten the constant sinus infections.
