I was given Avelox for a sinus infection that would not clear up with other antibiotics. I only took 3 pills before I refused to take any more but had effects right away. I had 5 hours of sleep in three days and all of the joints in my feet and hands ached. Eventually, two of my toes are now deformed and a week after coming off of the Avelox, my pinky finger turned in on my right hand. I also had burning sensations throughout my body, tingling and numbness.
