I started having nausea and lightheadedness every day, along with awful heartburn almost 2 months ago. A couple weeks later I added stomach pain and headaches to my symptoms. After lots of blood work & finally an ultrasound, I was diagnosed with a gallstone. Gallbladder came out 12 days ago, but first 2 symptoms, headaches, and now a lower, twisting stomach pain remain. Head MRI and abdomen CT normal. Doctors have been unable to diagnose. (Ultrasound did find 1 small fibroid in uterus too.) ???
