I had pretty severe rib pain, but I felt it in the back on the right side, not the front. It was terrible, nothing could distract me, and I could barely move. I ended up going to a chiropractor who worked with pregnant women and it was immediate relief. The pain would come back after a few days, so I saw her twice a week until I delivered. It was a lifesaver.
I hope you can find relief, it's awful!
