I have found pain relief using BIOFREEZE ,Your P.T.,or 1-800-FOR-ILEX .Another approach micro-currents also brought relief .You can see I was willing to try anything .The exercise program which uses random commands hopes to by pass the normal pathways wich P.D. destroys. This has also helped .Please be patient with my typing ,at 77 its hard .Thanks to everyone.Phyllis .
