bronchitis
"Was given this drug following severe bronchitis due to chronic dental inflammations.  By day 3, I realized my left ankle was painful and hobbled.  

I read the black box warnings and immediately discontinued the drug, however, that ankle and then the other one got progressively worse.  I was barely making it to work and back, trying to do eldercare solo, and thinking I was going to be crippled for life 6 months later.  Was seriously looking into joining class action lawsuit and probably should have, but no energy left over.  Think megadoses of magnesium and supplements plus some homeopathics like Thuja finally tipped the balance, and I gradually was able to walk normally without pain again.  Used Oil of Oregano to clear the infections."
