I was prescribed lavaquin for a staph infection. I took two 500 mg pills for 4 days and then one a day for 10 days. On the 10th day I developed severe pain in my knees and calves. I continued taking this antibiotic until it was finished (four more days), since I was worried about the staph infection returning. However, I now have pain in the middle of my back plus the pain in my knees and calves makes it difficult to walk and is very painful unless I am sitting. I just hope that I will recover soon. I will NEVER take this medication again.
