Bad sinus infection which almost cauesd my eardrum to burst. I took my first pill(500mg) of Levaquin on a Monday afternoon and the 2nd on Tuesday morning. That Tuesday night I noticed my hands were ver hot as I rested them on my stomach...thought I had fever so didn't think much about it. I woke up in the middle of the night and my feet were feeling funny and my left shoulder was starting to hurt. Took my 3rd pill on Wednesday morning as I lie in bed. When I got up my feet felt as if they on on fire. I could hardly walk. Both hands and feet feel as though the nerve endings are exposed. About midday, my shoulder pain had grown to feel like it had been dis-jointed(left-shoulder only). I have absolutely NO movement of my left shoulder. My knees also feel like they could give way at any moment. I cannot walk barefoot on anything. imagine yourself in the summer, about 110 degrees, walking on rough concrete....that would be mild. Wednesday was the last pill. It is now Friday and all pain is still there. Waiting on call from Doctor. I would NOT advise anyone to take this stuff!
