Hello, I'm 19 years old and when i get home from work and lay in bed it hurts so bad to roll over that it wakes me up at night my knees hurt, and every muscle from the waist down is in pain that's so bad that i loose my breath, i can't sneeze or it gives me the sharp pains and i don't know what's wrong because i'm so young. I shouldn't feel like this can anyone tell me what's wrong.?
