Sinusitis
"I was prescribed 250mg of Levaquin after the ZPak didn&#039;t help my sinusitis, and the Levaquin didn&#039;t help either.  After the 3rd day I had pain in my Achilles heel, fourth day, I had nausea and vomiting, however I just felt weak all over.  The pain in my heel went away, but again a week later on my 9th or 10th day, I had nausea and vomiting again, and experienced vision problems with all those funny floaters in my eyes. I thought I saw spider webs all over, very disturbing and lightning flashes. I don&#039;t feel it was worth anything to me."
