if you can't get the physio, google for good exercises and set up and stick to a regime of stretch and strengthen.

If you can get hold of a TENS machine, even better. They are pretty inexpensive these days and carried by most chemists (pharmacies).

I've never broken a bone, but I have rheumatoid arthritis so get a lot of joint stiffness and bone ache. I have a little trick for bone ache. Believe it on not, one of those microwaveable neck pillows filled with wheat kernels, but keep it in the freezer. It is not has cold as ice pack, but incredibly soothing.

Good luck. May you be strumming, knitting, sewing, etc very soon.
