Reached for box above head 45# while I was on the 2nd step of the step latter, took it down twisting torso to the top of the step latter 3rd step, right away a sharp pain happen and I could not take a deep breath. Iced right away, a week later I start having severe pain on my back, specially after lay to sleep, I wake in 3 hours after going to bed with horrible pain, upper, mid and side of back,can not go back to sleep. During the day the pain is there, can not turn to the sides, bend my neck down, but is less severe than at night, but still hurts, Pain upper back, mid back and both side rib cage. MRI and X-Ray back normal. What can I do to get better? I did physical therapy, massage therapy, chiropractor and now acupuncture. Any muscle relax, Tylenol does not help. I stretch at least 2 times a day. Any help? Never had this before, just started after the heavy box incident. This have been going on for 6 months. Any ideas to what happened to me and I can do to get better?
