I’ve used Cipro and levoquin during bad exacerbations over the years. It worked great. I will caution that it can affect your tendons. Once in a yoga class I was stretching and pointing my toes and they went into a cramp like a charlie horse. When my toes finally relaxed I had nerve damage and one toe sits higher than the others and doesn’t bend the way it used to. Also periodically my Achilles heel would ache a lot and I did worry about that tendon as well. Just something to keep an eye on.
