Worked very well for me, but I don’t know what my problem was or if it was the same as yours 🙂
One rolling session and my persistent acute run-limiting pain was completely gone – for about 6 months, then it needed another session or two per year.
There is little evidence to indicate foam rollers work
They may not work for all the things people claim; they may not do anything in most cases, but it sure as hell worked for me. However as said, I don’t know what was actually wrong with me. I’m not talking about a bit of an improvement, I’m talking about limping home after 3 miles to running 5 with no pain.
