I like foam rolling, and it sometimes helps me with back ache, but I wonder if it's possible to fall in love with it too much.
I used it on my IT band for ages, enduring horrible pain which never got any easier. I now think that was a total waste of time: trying to stretch the IT band is like trying to stretch out a truck tyre - it's just not going to happen, and especially not by foam rolling.
Second, about foam rolling through the pain. Well, maybe it releases 'adhesions', and that takes a lot of work...then again, maybe not. With sports massage, it seems to me that too much pressure only serves to bruise the tissue - going back to it before it's recovered just bruises it all the more. I wonder if continually rolling the same spot is just like punching yourself until you get a really sore area, then punching it some more and wondering why it still hurts.
