You should be aware that there could be two separate issues involved, and some of these posts seem to be confusing them. Cipro can cause joint and muscle pain, which can be severe. Although it's uncomfortable, it's not a major issue because these go away, as someone mentioned, once off the meds for a few weeks. If a tendon actually becomes inflamed or damaged, that does not go away once off the meds.
I took Cipro/Levaquin to treat pseudomonas for years. Joint pain became terrible at times, but I didn't want to do IVs, and just chose to deal with the pain and stiffness while taking it. However, I eventually ended up with tendonitis in my ankle (and some other complications) and had to stop taking it. That was a number of years ago, but the tendonitis issue still comes and goes.
From my perspective, the difficulty is telling the difference between joint pain and tendonitis. I hurt so badly, the slightly different ankle pain was ignored until my ankle started giving out on me periodically and the resulting stabbing pain got my attention.
Anyway--for your daughter's sake, I wanted you to know that while she might choose to fight through joint pain, she needs to be careful about the tendon issues.
