I feel your pain... I got tired of it pretty quickly so drug out my chair massager and put the setting on middle and lower back and let it do its work several times a day and man oh man had it helped. I have not had any bad aches for over a week now, and IF I feel even a twinge I turn it on and sit for a couple minutes and poof it is gone.
This is not an expensive massager, just a cheapy one we got from Wal mart years ago, I think we paid like $30 for it. It does the trick and that is all that counts.
