sinusitis
"Took this after having a sinus infection for four months, amoxicillin,  augmentin, zpacks, steroids,  nothing worked. Levaquin made me feel better within days, completely cleared the infection.  Did give me a swollen foot/ankle, but that cleared once I finished the antibiotic course.  I'd rather wrap my foot for two weeks, than have a sinus infection for four months.  I don't think this is typically prescribed unless other antibiotics have failed. On it again for another stubborn sinus infection,  no tendon issues so far."
