Don’t get dispirited by all this. Nighttime is awful for the first few weeks. I too was keen to not take too many pills, but as the admin here will no doubt tell you, that’s not a good idea. I ended up taking max everything before bedtime, a reasonable night makes such a difference both with the physical and mental state.
I managed to extract some zopiclone sleeping pills out of my doctor, they really don’t like prescribing them, but then they haven’t had to endure what you are going through. I took a half every night for a few weeks, they don’t last all night in the face of such pain, but it got me off to sleep to start with for a couple of hours and helped to get me back to sleep after a session of wakeful despair, a few tears and tantrums and much arranging of pillows. I then graduated to a whole one for a week or so as I had become tolerant to them. Then things started to improve, so I went on to non addictive OTC sleep aids, and now just take something if my knees are particularly bothersome.
That awful tingling comes, I believe, from inactivity. If it’s in just one spot, I found that a hot water bottle relieves it (away from your knee, of course).
One thing that I have only fairly recently discovered is that anti inflammatory gel massaged into the knee helps in the night, ibuprofen gel or even better diclofenac gel. The latter is only on prescription in the U.K., luckily I am able to buy it from the chemist here. There is the opinion that you are then overdosing on the anti inflammatory, but it hasn’t done me any harm, only good. If you don’t have heart problems, then you may be able to get some on prescription.
Bottom line, have a word with your GP and lay it on thick. Things will improve in time, then it will be easy to start weaning yourself off meds.
