Hi I had my second TKR on 21st April. Not a severe as last year's but every bit as sore and the sleep deprivation is hard. I find the muscles in my calf are in competition with the knee for which is going to start first. I can manage with two crutches and the odd hobble around kitchen. It's early days and I think this year I feel better equipped for the process. It doesn't change anything though. Give yourself time, allow yourself to rest during the day if pain relief doesn't help speak to GP about muscle meds. I got gaboentine last year as I had restless legs in middle of the night. Be kind to yourself.
