I was prescribed Avelox for a sinus infection that would not go away. After 4 days of taking it I have had severe cramping in my joints around my ankles, knees, shins and calf muscles. I have pain in my fingers too. I feel totally out of it, and dizzy. I have little to no appetite. This is a terrible drug, and should be pulled off the market. I was desperate to get rid of my sinus infection, and now I find myself having bigger problems from the side effects of this drug. I have had pain now for 4 days. Does anyone know when this pain goes away?
