It's hard to massage the middle of my back--no one available to do a gentle massage; at least during the day. Using a heating pad helps quite a bit, as do muscle rub creams, though that, too, can be hard to apply to the right area. Is this area something for the 'tennis ball massage' or something like that? I should buy one to have on hand.
I've done some mild stretches which helps a little. Also changing positions as often as I can. Other suggestions?
