I'm terrified of this feeling, its a rushing sensation up my leg and sometimes my arms or the other leg, it just feels as if the blood is rushing violently up my leg constantly, i got this feeling when i was taken to hospital for smoking cannibas years ago, allthough then the feeling was through my whole body and it was 10 times worse! That really messed me up, never touched drugs again. But im sitting here and im getting this feeling through my legs now, and im in tears because of it. Im so scared, what is this?!
