Awaiting hip replacement surgery

Good afternoon. I had a successful left TKR July 22. Surgeon and physio were pleased with recovery with good range of movement etc and was discharged after 12 weeks. My six month check showed all was still good. I have since been diagnosed with right hip arthritis and am now on nhs waiting list for surgery. I am quite concerned of the adverse effect to my TKR as it is ‘taking the load’ from the opposite hip and can be sore and a little painful at times after a busy day. Is this a normal reaction? Thank you.
