I have had muscle neck and shoulder rigidity (stiffness) In my left shoulder blade for about 1/2 years now. When I want to look left I have to turn my whole body around, went to GP and because I have sponderlitis in my neck, the GP told me this was this was the cause. I do Tai Chi twice a week to keep active and this helped my shoulder. When I saw my PK nurse she referred me for physio, I had also been referred by the pain clinic to receive acupuncture on my back. It took my visit after seeing my nurse in Aug 2014 till March 2015 to see the physio, after consultation she told me that there was nothing she could do for my shoulder, all she could offer was a little excise. In the mean time my appointment came though for my acupuncture, I told the nurse/doc that my back was OK now, so she advised me to have the acupuncture on my shoulder, I now have had it 3 times and I am amazed the stiffness has almost gone, I can turn left with out moving my whole body. I must admit I was a bit apprehensive at first but hay if its works then I'm all for it. Is the stiffness due to my Parkinson's I don't know but it's just nice to be able to turn left again, and lay on my left side to sleep.
