The knot shows up in your back, but the strain starts in your neck

The nerves that serve the inner edge of your shoulder blade branch off your spine up in your neck, then travel down and across your upper back. Some carry on into your arm and hand.
Spend enough hours with your head tipped toward a laptop, a phone or a steering wheel, and those nerves are under steady pressure. Your body reports that pressure where the nerve ends: the exact spot you keep reaching back to rub.
Ever noticed it gets worse after a long drive or an evening on your phone? That's your neck talking, not your back.
