Yes, thanks Zakyrus, I have tried the last two days, but have had to give up each sitting meditation as I could not stop yawning each time, so I have just done the active exercises followed by the ending exercises. When I stopped the Harmony of Universal Energy , I held my hands over my lower dantian for several minutes and my fingers had like pins and needles which then seemed to flow up to the base of my neck which tingled too, then my feet.

I am still working on the shoulder etc, but with no change yet
I won't give up :-)
