I have had previous CT scans that have shown bulging discs in my back. The left side of my back close to the bottom of my ribcage has always been uncomfortable for me and yesterday while I was feeling around I found what seems to be a hard spot inbetween what I think is my last two ribs. It is uncomfortable to touch and now that I have pushed on it and manipulated it, it is very painful to the touch. Almost like it's bruised. I am a very active 28 year old woman, and I am not overweight. 6 feet tall and 147 pounds. I receive massage therapy often as my muslces are always very tight. Could this just be a tight muscle that needs to be worked out? Are there muscles in between your ribs in your back?Or could it simply be inflammation that an anti inflammatory would help. I should mention that I have been put on prescription anti-inflammatories to help with the inflammation in my back.
