I had a bad fall in the Military and my shoulders and arms are numb from time to time I also notice a cracking sound when I turn my head from side to side. I've been told I have degenerative disc diaseease at c4,c5 and c6 They tell me there is narrowing and bulging. But refuse to operate I've been told cause I am to young meaning not near retirement age. I also have problems at l4,l5 and s1 which causes pain down to the knees and ED. undetection of the need to use the rest room.
