bronchitis
"Sick for three weeks with sinus / ear infection that spread to the lungs.  I was first given a "z pack"  which did not work.  Got really sick and ended up getting fluids, Levaquin, and prednisone.  By the third day I was feeling much better.  I'm on the medication a week now, no problems other than a little jittery, but I believe the prednisone is contributing to this side effect."
