“I don’t think it’s anything major,” says Dr. Ara Suppiah, a physician to several PGA Tour players. “I’d say most likely it’s a muscular issue and here’s why: If you have a fused spine, different parts of the body suddenly have to pick up the slack for that lack of mobility, and those compensations can lead to issues in other places. And a neck issue is a real issue for a golfer. The head stays still for a good portion of the swing but not all of it. And when it does have to move, any pain or discomfort can really affect the golf swing.”
