J.T.
I think the Tempupedic is the best mattress for all types of back pain. We tried the Sleep Number bed (the one with the air mattresses in it), but we didn't like it even though many people swear by it.
I have had low back issues for years and have mastered sleeping on my side with a pillow between my knees. I even have the presence of mind in my sleep to keep it there when I turn over to sleep on my other side. If I ever get through the night without the pillow between my knees, my back hurts like hell the next day--guaranteed! You can by a "pillow" designed for using between your knees, but I didn't like it. My husband and I call my sleep set up "the pillow fort". I have a contoured one for my neck with a squishy down one on top, a medium thickness pillow between my knees, a fluffy one that I hug, and sometimes I put one on the bed behind me against my back. Sounds like a bit much, but if I could sleep in a tight cocoon I would be very happy. I must of loved being in the womb!
Good luck to you. I know how much back and neck pain can suck the joy of life right out of you.
p.s. I have had wonderful success with good chiropractors over the years. (I've also pissed away a lot of money in the process of finding those good ones). Such a pain in the . . . well, neck!!!
