I have taken almost two complete 7-day rounds of Leviquin and just today realized that my aches and pains are probably due to it instead of chronic fatigue or fibromyalgia. I will not take those last two 500 mg tablets! I have extreme joint pain and swelling of the wrists. I have been blaming lower back pain on the 16-hours of sleep I had on Sunday! My hip joints hurt so that I can't raise my foot to step into pants when dressing. I'm sure I read the Rx paperwork when I filled this prescription, but don't remember seeing extreme pain as a side effect. Why didn't my doctor warn me?
