I took Avelox, on the second day i woke up with red itchy spots all over my legs,,, they started to spread and became so swollen,,, for the 4 days i walked with my legs being in so much pain and burning sensation around those spots,, then spots turned more like stones,, they harden so bad ,, i couldn't even sleep,, by accident i forgot to take my 4th dose and on the next day i noticed that swelling came down a little ,,, i still went to doctor and she said to me ooooo i am so sorry,, this is so rare but it is a side affect to Avelox, and obviously i stopped the medication,, I have checked with Nutritionist and Natural Care doctors,, and i was told that the best way to flash this antibiotic out of your system would be drinking a lot of water and also get Natural Aloe juice,, in Organic Health stores, and drink 8 oz,, 4 times a day...!!!!! Try it,,, it works
