Sinusitis
"After 5 days of terrible dry hacking cough causing chest muscles to be sore and being unable to function, I went to the Dr. and he prescribed the Z Pak. On day 2 and I see results. It is loosening up all the congestion. I am finally a little better. I have a ways to go but I do see good results.  When I talked to the pharmacist, he suggested eating something light before taking even though you can take on an empty stomach.  He said some get upset stomach after taking so I took his advice and having no problems.  I tried Mucinex before seeing the Dr. but got no results this time. Glad I went in for a checkup."
