Back injury

Patient: I twisted my back at work the other day and now my right leg is asleep constantly and It feels like I have one big charlie horse all up and down my leg. can you tell me whats wrong?

Doctor: You have definitely pulled a muscle. I would take it easy for the next few days and get plenty of rest. Try and do lots of back and leg stretching exercises. If this does not help, I would suggest following up with your doctor for an in person examination.
