Bronchitis
"I am rarely ill so have not taken a lot of medications; I also have a sensitivity to medications.  I told this to the prescribing physician when seen for bronchitis. She prescribed avelox and by day 3 I had developed large red welts; went back to the Doctor who determined it was erythema nodosum.  Avelox was overkill for someone like me - it was way to strong and this was a horrible side effect."
