my son is 2years 9 months old. he is having knee pain since last one month. Admitted in hospital and found that it is Post covid. so treatment goes on and discharged. they have given steroid syrup. again knee pain even in the time of taking steroid. Now aborted in another hospital. They taken urine culture and find that UTI it's there. so giving treatment for that infection. So, I have a doubt , will that UTI causes knee pain ???? Knee pain with fever, no swelling in knee .
