Sinusitis
"My dosage of Levaquin was 750 mg daily initially for 5 days &amp; later extended for another 10 days after an ER visit. I discontinued the drug after 11 days due to: a) a general feeling of malaise after taking the drug  b) I am a runner and I began experiencing tendinosis in the Achilles tendons &amp; then on a routine run, I pulled up lame and could not continue due to severe pain in my left hamstring area - I attribute these injuries strictly to the Levaquin.

I think this drug was effective in handling the infection but its side effects for me as described above are very real.  I will not take this drug or probably any drugs in the fluoroquinolones class again. Anyone who is into exercising should think carefully about using this drug."
