Make sure that you don't exceed the safe daily total of 4,000 mg Paracetamol in each 24 hours. It may be best to take the Paracetamol 6-hourly if it seems you are going to exceed that safe daily total.My prescription was Tramadol three times a day but I honestly don’t need that much so have cut it down to paracetamol 1000mg every four hours during the day and a Tramadol and paracetamol 1000mg before bed.
United KingdomAre you icing and elevating during the night, too. I found doing this to help tremendously.I find I have very little pain during the day (as I’m icing and elevating) but pain ramps up as I get ready for bed.

Well done @snootsI went to Physio yesterday just for a therapeutic massage and she casually mentioned that protocols have changed and now PTs in UK are encouraging patients to push injuries to point of pain but not beyond. I just ignored her and haven’t rebooked!!!
United States@snoots I swore by my tens machine pre-op. It was the one thing that really helped with pain. I used to wear it at work to get me through a shift. I have been too scared to try it after the op. I have a large numb spot that I hate touching so didn’t fancy trying tens.

United KingdomThis article has an illustration of where to put the stickers:Can you tell me whereabouts on the knee the PT puts the stickers?
