Levofloxacin
"I now wonder with me having this medication last year if it did not cause my Plantar Facitilitis that I have horribly.  I am on day 7 of 500 mg and I  am coughing so hard it makes me vomit. my tonsils have went down but  I do not sleep well and my mind always thinking. No down time. Stomach is upset and I am hungry but can't eat. I have 3 more days to go and I don't think I am going to continue."
