Hi Chaffinch. I had both knees replaced because of osteoarthritis which attacked where I had previously had bone cancer. I have quite bad back problems and am now having problems with my right hip as well. Part of my problem is that the sciatic nerve is badly damaged, but there is also quite bad osteoarthritis. My doc tells me to take 2x30mg codein 4 times daily, 2x 500mg paracetamol 4 times daily and 1 Naproxin 4 x daily. It is helping a fair bit, but still doesn't kill all the pain and to be honest, the codein makes me feel tired all the time. What does seem to help is taking a rest in the afternoon, about 30 min. to an hour, if and when I can. I also put a pillow under my knees when resting on my back, to raise my feet a bit and when sleeping on my side, put a pillow between my knees and lower legs. This too helps quite a bit. Be careful with the exercise, as if this is arthritis, then you can cause more pain and inflammation by overdoing it. Keep mobile though! I also use Ketaprofen gel, which I understand is now going to be discontinued and replaced with ibuprofen gel. Hot water bottle always helps too. Main thing is, stay positive and don't let this stop you from doing what you want to do and leading a happy, productive life!! Hope you feel better soon!
