sinusitis
"Colds turn into sinus infections pretty easily on me. Yes I wait a while before I go to the doctor for antibiotics as most sinus infections are viral. By the time I went to the doc with this one I was MISERABLE. Hurting down into my jaw even. Within a few hours of taking the first pill there was relief. I never knew I could have so much disgusting stuff come out of my nose. I always take probiotics (especially while on antibiotics) to decrease GI side effects. TAKE PROBIOTICS. Nausea and diarrhea are possible with any antibiotic."
