hi, good morning. my 11yr old daughter tested +ve for covid 19 last week. her symptoms were mild, now she only has slight cold n cough. she has been complaining about pain in her right knee since few days - it seems to have started after covid. its painful when walking or moving. she is able to stretch and rotate normally though. kindly let me know if this is normal post covid effects or we need to consult an ortho?
