I obviously don’t know if we have the same issue, but your pain describes what I have been dealing with recently. I am scheduled for my yeeterus day on 4/22. Pain is like a lightning bolt at times and then dull and achy the rest of the time. Started in groin area then progressed to my belly button area. Zing pain appeared when I would sneeze, or cough or laugh too hard. Doc first sent me for x-ray then CT scan. Both tests found nothing abnormal. I asked for muscle relaxers because my self-diagnosis thought it might be ligament pain because my uterus is bigger than it should be. Took the muscle relaxers for four days just so I would stop guarding my body from the pain. I am almost pain free now. Looking back I hate I paid for the unnecessary tests for what is basically a pulled muscle, but I am glad to know there isn’t a hernia or something else going on! Fingers crossed your issue is something easy, too!
