How often have you had the dose increased? Have you told your Dr that it is not helping? I've only been increased about 4 times since 2012. The only other thing I can think of is the addition of a pain stimulator. I knew someone who had both and it seemed to help him. What other things do you do? Hot tub, swimming, meditation or yoga might help. as you know this is a journey of trial and error. For instance, heat helps me. The only exercise that seems to help is warm water exercise, like the one at PT. Have you tried Voltaran? The anti- inflammatory gel that you apply on the skin? I hoped this helped.
