I think you are very lucky.

Most of the web sites I found on fluoroquinolone damage, report it as permanent.

It might be connected to individual genetics, and for some people therefore might resist the damage that is more severe for others.
There is some evidence that this genetic weakness is a factor for statin damage too.(i.e. more likely serious in some and not others).

You are however not out of the woods in regards to your tendons.
Ruptures can occur any time after a course of fluoroquinolones, so be moderate in your lifting or stretching. We've had two male posters here pop their bicep tendons after these drugs.
