I've had this issue since last October and I'm really hoping that someone can help. I've had a pain in my upper back (mostly the left side) that sometimes extends to my chest as well. For a long time, everything felt relatively normal except for when I would sneeze or take a deep breath. When I did either of those things, it would hurt pretty bad. Like a sharp pain. Luckily, now I can sneeze and it generally doesn't hurt, but breathing is an issue and often my back/side/chest feels sore. I initially went to a PCP who sent me to a lung specialist. They did a CT scan and blood work and reported everything normal. For the past 2 months or so, I have been going to a chiropractor hoping that might help things as well. Any relief provided by the beds is short lived and comes back within an hour or two. The only thing that has worked really at all was being prescribed a high dose anti-inflammatory drug. That helped, but the symptoms reappeared within a couple of weeks. Sometimes it helps to rub my back, chest, or side, but again the pain comes back. Any thoughts or clues as to what I might have? I thought I might have a rib out of place, but wouldn't the chiropractor see that on my x-rays or the lung specialist with my CT scan? Thanks for any advice.
