After taking Levaquin for 7 of the proscribed 10 days, I awoke with severe lower back ache, running down the front and backs of both legs. I did not connect the pain to the drug, as I have seen a chiropractor for similar pain. He said that it was highly unusual for a back issue to effect both legs, and that the hamstring pain must be some unrelated, coincidental muscle strain. After my treatment the pain got progressively worse. I could not sleep, and drank milk to ease the cramping in my legs in the night. The next day, I discontinued use of Levaquin, started drinking gallons of water and green tea to purse my system. On the 8th day, I strarted with the nausea, which I treated with crackers. No nausea on the 9th day. Receding muscle pain the night of the 9th day, and last night, the 10th day, receding still. Trouble is, the pain seems to magnify when I sit and espcially when I lay down. I am moving around pretty well during the day now, but my ability to sleep has been impaired and finally seems to be improving. Last night was pretty good.
