A member asked:

Burning sensation under left knee in when trying to touch my toes sitting flat on the ground. im 16, any idea what causes this?

A doctor has provided 1 answer

Hamstring tightness: The location you described is that of your hamstring tendon. If it is tight, when you try to stretch it, it will burn and hurt. Continue to GENTLY stretch it, and eventually it will loosen up and the pain will fade. Hope this helps!
