i play golf a lot (every day) and have recently been getting lessons. my coach told me that parts of my golf swing may make my back hurt, so we worked and started doing it the right way. but recently, in the last week or so, i have began to feel pain basically only when i swing a club. i can do everything else fine. im just wondering why this is happening and if there are stretches, drill, etc i can do to relieve it and to prevent it. thanks i appreciate it its really hindering my game as well.
