sinusitis
"I usually get 2-3 sinus infections a year, usually starts with a cold then comes the sinus infection. Azithromycin is a miracle drug for me. I was seen by Dr today and the pain was so intense it caused my blood pressure to be high, she prescribed me  zpack and within hours after taking the initial dose the pain is 50% less.  I do not have any side effects from the medicine and it is the only prescription drug that works this well on my sinus infection"
