I have been taking levaquin 500mg for 1 week. I went to the dr. for the FLU and was given zithromax, I returned after 3 weeks and was given levaquin 500 mg. After one day both feet got cold and I was unable to walk. After 5 days of pain in both feet, pain moved to left foot only. After 7 days, pain moved to left knee, still cant walk. Looked up side effects on internet since they weren't in pharmacy pamphlet, and after reading, quit taking Levaquin. Called pharmacist and was told that levaquin had nothing to do with leg and foot pain. Does anyone know when the pain goes away?
