Anthony2068

i am a 21 year old college student, and i am experiencing moderate to severe pain. The pain starts from my buttocks and travels sometimes all the way to my heel. the sensation feels sort of like i am stretching my leg constantly, even when laying down it doesnt stop. it is only in my right leg, and when i walk i cannot move my right leg more then a foot or two in front of me, like say trying to kick. If i do, i get very severe pain all through my leg and it simply wont go any further. when i do try to stretch the muscles in my leg, i feel tightness or pain in my lower back.

i wish to keep attending school, but its becoming very painful and hard to focus. please help. thank you for your time.
