If your legs aren't working so great, it's probably nerves. Maybe they can make some improvements. Don't wait too long to find out. My friend ruptured a disk and there was a flap of cartilage pressing on a nerve. She was losing feeling in one leg, foot went numb. They scheduled the surgery right away and dr couldn't guarantee full feeling or use. She's better now, so got lucky.
Isn't there anything that can be done to help? Were you a wild thing when young? Blow your ears out at loud rock concerts?
