Certainly the most painful way of spending £15 I've found so far. Absolutely agonising at first, but I have got used to it... to a point.
I got it to try and sort out ITB too and while it helps, it hasn't fixed it completely probably because I'm not disciplined enough to use it every day. Anyone else with ITB problems have particularly painful areas at the top & side of the thigh? Can't seem to get rid of that area of soreness at all.
I should probably stretch more too, but always forget to do this when I've warmed up. I've read that you shouldn't stretch when your muscles are cold, is this right?
