I have taken Levaquin for 3 days now and I feel awful. I am not taking another one. I have a spot on my lung thought to be pneumonia but undiagnosed now. I feel like I have a bacterial infection.

I have a question I hope you can answer. I have the muscle aches, headaches, neck and back pain I don't know if it is from Levaquin. I was given that in November after I had a bad sinus infection and was wondering if this can still be an effect of the Levaquin. My doctor is puzzled and less than helpful these days.

What are the long term effects of Levaquin and are bad side effects a "normal" part of this drug?

Any help is appreciated.
