This is my first post on the knee forum although am a regular on the hip side having a right THR on 13th July 2018. I have had lots of knee pain over the years and since my car accident in 1985 have always needed to use a soft mat when kneeling down. However, since my THR my left knee has been so much worse. Pain killers don't seem to touch it and it's permanently swollen and feels hot. I get my xray results tomorrow and expect it to show that I need a replacement but don't see the OS until 1st Nov. If I am to have surgery it will be a long wait on the NHS. Is ice likely to help in the interim?
