I have had a good amount of tendon pain mostly in left achilles
and in tendons on top
and bottom of arch of foot as well as some heel
and knee pain. Again, like I said primarily left side. The achilles pain has subsided some, most of the pain and discomfort now is in the foot.
I have taken quinolones a few times in the past (Cipro) with either no pain or some pain that subsided quickly at or shortly after end of course (same with left leg/foot, I think).
