Just some simple questions that i feel could do with clearing up;
1) Is it safe to use the foam roller on the femur (thigh) bone? I ask this because when you get into areas like the quad and adductors then i sometimes notice i can feel the thigh bone and it causes some discomfort but i don't want to get that too confused with trigger points as i know the difference as i can feel the bone on the roller. I assume it's safe as some people even use PVC pipes for these purposes?
2) Sometimes when i foam roll i feel the "Knots" ping apart, i guess the easiest way for me to describe this is if you take an elastic band and pull it back and release, sort of like a slingshot. I notice it on areas like where the it band/quad is near insertion at the knee cap, sort of like when you roll over that area, the roller gets into a slump and then jumps back up, almost as though it's a ridge. Lousy explanation i know, but just wondered if this was normal?
3) Similar to #1, i have trouble rolling my lats, when i do so, i feel the roller dig into my ribs a fair bit, my roller is pretty firm, but i find this discomfort makes it very difficult to roll my lats, should i stick to just trying to stretch them instead?
