My 66 year old mother had her right hip replaced in May of this year.   She has been very active and doing basically everything she wants since July. She started complaining of her hip bothering her about a month ago.  Now she is in the hospital with pyelonephritis.  In the passed two days, she has said the pain in her hip now severe and is running down her entire right thigh.  Could her hip be infected and causing the pyelonephritis?
Howell come to ChatDoctorHip pain and pyelonephritis are two different condition, and they are nothing to do with each other, it would be very less likely that because of one condition other affected, because of the infection body pain and major joint pain may be likely and this may not be indication of infection, if this is pyelonephritis then this need to be treated first, hope this information helps, take care, have a nice day.
