I took cipro for two and a half days and now i have popping joints and tendon pain all over

hi everyone. i took 500mg cipro pills twice a day for about two and a half days for a suspected infection and now im having popping joints, muscle spasms, and tendon pain everywhere. i told my pharmacist and he told me to stop taking it. im only 18 but I’ve had some mild tendon problems in the past. im on nystatin too should i stop taking that? am i going to be okay?
