I bought this little comfort item at Walgreens almost two years ago and I can't imagine life without it now.
In case you can't tell from the picture (which I realize is totally unnecessary but I like taking pictures of stuff), this is a Homedics shiatsu massage pillow. It has two rotating heads (I guess that's what they're called) that also heat up. The great thing about this massage tool is that you can place the heads right on the spot that's giving you trouble, unlike those chair massage things that only cover a strip down your back.
This pillow works great to massage and relax the muscles in my mid back and it really digs into my trigger point areas. It's a total lifesaver when my back is tight and hurting and when my trigger points are acting up. I use this pillow almost every day and there have been many times that I would never have made it through cooking dinner without spending a few minutes with this pillow.
A couple notes of caution: If you leave it plugged in, it stays warm, which I find a bit disturbing. Also, if you are really tender to the touch, this might be too rough for you. The heads stick out quite a ways and they are rather hard.
Another comfort item that I couldn't live without is a big styrofoam cylinder that I bought from my chiropractor. He called it a myofascial trigger point release...Hmmm, I seem to have forgotten the last word but, boy, does it feel good on my trigger points.
It looks like this:
You place it on the floor and then roll on it, spending time on any spots that hurt or feel tight. I think it really does help to release the tension in my trigger points and it definitely works out tension in my back.
It's pretty firm, so if you are really tender it might be too hard. I saw something like it in the yoga/pilates section of Target, so you could always sample it there to see if it would be comfortable for you.
