Sinusitis
"I get a very bad sinus infection every year. This year as soon I as I felt in coming on (day 4) thats early for me, I went to an urgent care. Doctor confirmed it was a sinus infection and have me the Z Pack. First day is 2 pills with 1 pill for next 4 days. After 12 hours of taking first 2 pills I felt so much better.  I will continue to take the remaining pills and from now on I will get to a doctor  early on and request Z Pack. I highly recommend it."
