I injured my back pulling fence posts out of the ground approximately 5 years ago. My family doctor prescribed physical therapy which I did, along with the take home exercises, and while it helped, it never totally aleviated the pain. Fast forward to today, and I've tweaked the old injury. Most of the time now it feels like I have an ice pick stuck in my left shoulder blade, and my lower back below my waist hurts as well. At times it hurts to cough, so I'm trying to determine the best course of action. I don't know whether to go to a spine clinic, chiropractor, or ???? Appreciate any suggestions you may have. I'm 52 years old, 6'2 220 lbs. Thanks.
