I’m having physio for the same thing. I have started doing the physio excersises as much as I can during the day, when I have the heating on and the house is comfy. My Gp wrote to the hospital telling them they were useless, since then appointments have come my way. A very good physio lady has been treating me. I think on the quiet, she does quite a lot of research for my problems and treats my pain/stiffness etc as an individual thing not just a blanket problem. So for me she is brill.
I also at this time of year as the stiffness always get worse, go for massage. Yesterday was my first for ages, she did the head neck, arms and hands. Sometimes this is the only way I can feel what is going on in my body. When she presses and massages, I can tell which bits feel better or worse, which bits are lumpy, stuck, stiff etc and also I can ask her opinion. Yesterday, to me the left felt worse, my massage lady said that actually the right is tighter and less responsive. So now I can tailor my excercises to give that right side a better work out (whilst watching tv). I have a lot of feet excercises too, all of them are tailored so that I can either do them standing, sitting, or in bed which is very helpful as I am not always up and about.
Last year, I had trigger finger and my hand didn’t work so I am determined to do as much as possible to prevent that happening again a lot. It will a bit, as it is now an intrinsic fault within my arm, but I hope to minimise it and keep it as flexible as possible. Hope this helps. ps It took a total of two years for me and my GP to get the physio appoinntments properly.
