My boyfriend keeps getting an electric shock pain in his back when one spot on his spine in the middle of his back is touched. what's wrong with him?

Mid back pain: Without more clinical information, it's difficult to say what the precise diagnosis is. Based on the limited information, it does sound like he is experiencing some sort of irritation or inflammation of his spine. It could be as benign as muscular strain and as serious as a thoracic cord compression. If he's experiencing symptoms down his legs, i would have him seek a formal medical evaluation.

See below: This is a problem that necessitates a face-to-face meeting with your doctor. This will allow him/her to examine you, ask specific questions. And possibly order tests to find out what's wrong and what to do to help you.

Spinal radiculopathy: It sounds like a pinch spinal nerve from either a slipped disc or osteophyte off the spine itself pinching the nerve root he should check that out.
