What Is The Treatment For Spine And Rib Cage Pain?

I HAD a pain location (as in image) left of spine and lower left rib cage, though not localized. That pain has subsided, however, I am left with a pain in the left groin area. It flares at night when I lie down, but it can continue after I rise. I think I feel a bit of pressure in the bowel, and my bowel movements are not as regular as normal. I recently traveled to New York. The mattress I slept on had no support. My diet has been good, including fresh fruits and veggies and whole grains.
