How much feeling are you supposed to have in your lower body compared to your upper body? For example, I have all feeling in upper but since I was born there has always been less feeling in the buttocks and lower. It starts near a pretty deep sacral dimple. Once I became sexually active I realized that I don't seem to have as much lower back/body strength as I should. Physio has confirmed that and said my lower back muscles are frozen. Are any of thee connected?
