I am having those issues. Started out on occasion and now more frequent. Sometimes extreme fatigue follows the BM. I have had endoscopy, colonoscopy, sonagrams of the middle, heart EKG, blood work. At wits end, as the heart racing continues for longer periods after BM. Doctor in ER, primary, endocronologist all never heard of the symptoms. Sure could uuse some insight, cause when the heart starts pumping its time to hit the restroom. I fear if I wait, I will pass out.View Thread
