Hi, I had a total knee replacement 8 days ago and I’m finding it really difficult to sleep for more than a couple of hours because of the pain. I’ve been prescribed paracetamol and gabapentin. I was also given tramadol which I’m reluctant to take as I’m allergic to opioids. I’m finding I can’t get comfortable and although I’m dropping off to sleep, it’s broken sleep, and I’m checking the time to see when I can take the next dose of painkillers. Can anyone offer any advice please, is this normal and will it improve as time goes on? Thank you.
