Awful flare up sent me to ER

Last night was one of the most painful moments of my life. I had a sudden very sharp onset of pain in my lower abdomen that spread to my right side. I was barely able to walk. I began shaking and vomiting. At that point I genuinely thought my appendix had burst or something. I went to the hospital and waited about 5 hours. Got bloodwork and a urinalysis and results were all negative. Doctor sent me home and said drink more water and eat more fibre. I’m still in alot of pain this morning. I’m a bit upset that he didn’t order an ultrasound to make sure it wasn’t a burst cyst or something else…

Just need to vent as I’m feeling really upset by this and overall unwell.
