Thanks for the information. I finally went back and made an appointment for next week. Mainly because I'm out of Synthroid (for my hypothyroid) and also because in addition to the pain in my right side, I now have a bump, more like a bulging, right at the lower rib cage, near where the pain is. It has me very concerned. I'm hoping the sonogram they did a couple months ago may show something, but I'll probably have to have another sonogram since it's been so long. Any thoughts on what this lump might be?
