Well its been a week and I had my first doctors appointment. She thinks the knee looks good, no signs of infection and the swelling is reducing nicely. The only bad points were my constant headache and thirst. They checked my blood sugars, all OK, and took some blood samples to check my platelets. The knee is gaining strength daily. I can walk for about 10 mins now with my walking poles instead of crutches. I can climb the stairs without crutches but still need one to come down the stairs though.
I've been trying to come off the codeine painkillers the last two days as I've been waking up covered in sweat after about 3 hrs in bed. So I've swapped to paracetamol, see how it goes.
