This growing belly is causing me severe sciatic nerve pain & it's awful! It goes from the top of my right hip/buttock and shoots down my leg making it uncomfortable to walk., and then a constant pain in the middle of my back on the right side. I've taken Tylenol and I'm laying on a heating pad.. any other ideas for relief? This has been going on for a few days, but tonight is the worst!
