Hi, I am a 48 yr old woman with a lot of back problems to begin with. But about 2 weeks ago I started getting this severe pain in my back ribcage. I only happens at night. I wake up with agonizing pain that if I turn, breathe deep, or anything. I went to the Dr, and he took X-rays of my back, (which is not where the pain is coming from) and they came back ok. I am getting worse every morning and hope you have any ideas. Oh, no urinary or bowel problems, just the pain. Thank you for anything you can come up with.
