I have fibromyalgia, rheumatoid arthritis and Sjorgren's Syndrome. It is hard to find stuff to ease the pain. I am under the care of a rheumatologist and on medications (cymbalta - fibro; cevimeline - Sjorgren's; and, plaquenel - RA).   I have found, however, that I do sleep better on a temperpedic mattress.  I have no stock in them and don't work for them!  It helps some, but at least it helps.  I am not as achy in the mornings.  Even when I travel now, I only go to hotels that have a temperpedic mattress option.  I don't know if you already have one, but this did give me a bit of relief.  I also find that water exercise is good.  I am blessed to have a pool, but if  you have access to one, pool exercises also help give some relief.I hope some of this will be of use to you.  I understand your pain and frustration.  I basically just do my best to live with it.
