I took 4/10 doses of levofloxacin 4 years ago, and it was just horrible. The symptoms were very similar to what OP described. Mine cleared up 90% after about a year, but continue to persist in small ways. I had an excellent rheumatologist who helped immensely through the situation (he had seen a lot of joint and tendon issues in his long career), but most doctors that I went to see dismissed the suggestion outright (including the GP that prescribed it).
