I am experiencing pain in my back, hips and both legs. This is severe at times and causes me problems when bending, when I have been sitting for a while, and is especially painful in my knee. This is something new for me and I don't know if it is related to Parkinsons or if it could be from arthritis. Does anyone have a similar problem? If so have any complementary therapies, for example the Bowen technique. helped?
