Developed Joint Pain After Infection - Seeking Advice

developed joint pain over 1.5 months after an infection - what do you think? I was sick in late August (likely caught something from the hospital I work in with patients on infectious disease precautions) with no symptoms besides strong fatigue. i had pain in my left and right hips for a few weeks before that, which only got a lot worse. I started having pain in my left calf, then my knee, then my right knee, then my shoulders and wrist. that all developed over about a month and hasn't gotten much better. I've had multiple CBCs throughout this time that told me I had an infection, then recovered from that but had a significant dip in platelets afterwards as my symtpoms got worse, and now my blood is normal (but again i still dont feel any better). I'll have tests for RF, CRP, and sed rate this week, but does this sound like anything in particular? I know a good number of people have similar problems but hit a dead end if blood tests are all negative.
