Sinusitis
"I suffer from chronic sinus infections and migraine headaches. I usually can tell if a sinus infection has taken hold when sumatriptan ( migraine med) is not working!  first go round a couple year ago with Augmentin 875 mg big pills was awful, and I experienced what others reported with horrible chemo like diareah effects, barely made it through 5 of 10 days, but felt better in head afterwards. decided to gut it out again a couple years later with another sinus infection after weaker antibiotics did not work and had a much easier time with augmentin. perhaps body needs to adjust yo this med, but thank god it works!"
