Has anyone ever had really tight hamstrings and actually managed to relieve it through stretching? My legs always ache, I get large balls of knots in my calves regularly and am now getting back pain and pain across the under side of my feet. I have tried stretches but it never seems to do anything and now it's having such knock on effects to rest of my body I'm getting really worried. I suppose I was just wondering if anyone else has had this and got any relief from the discomfort? I don't know anyone else who has the same level of inflexibility that I do
