I went to an internist for nasal congestion and he put me on levaquin. I was previously in very good health. My life has become a nightmare since taking ten days of 500mgs. I was dizzy right away but I decided to be stick it out because the print out said that dizziness could be a side effect. The pharmacy print out failed to mention that it could cause excruciating pain in the joints in my whole body and especially my knees. This was three weeks ago and I can hardly walk. I was a substitue teacher before and I cannot go back to work. I can't sleep from the pain and can hardly get up stairs. I keep hearing cracking noises when I move my body. I forgot to mention that I developed a yeast infection, burning skin, crawling feeling all over. I took Diflucan to get rid of the yeast. I want to walk normally again. I've been off the medicine about three weeks and I am feeling worse.I am taking Advil to help but I am not sure it is. Does anyone know how long these symptoms last and what can be done. I am frightened.This medicine is poison!
