I'm not sure if you're still having these symptoms, but I'm experiencing something similar now. I don't drink and my bilirubin has been elevated for almost three months. It was 3.6 and fluctuated from 1.8 to 2.7, the last check it was 2.3. I have heart palpitations and an increased rate, my blood pressure has dropped, I have vision impairment, nerve sensations in arms and feet, tremors, and for the last several days GI symptoms. Oddly enough, I had experienced this type of thing a little over three years ago with the exception of liver function involvement and came to the conclusion of vagus nerve disruption. The problem cleared up on its own, so I never went back to it. Back in October, I got into a car accident and had a mild cervical strain. A few days later is when the headache/vision/heart issues started. I'm wondering if I've aggravated my nerve with stress somehow. The last time the symptoms began, I had a mass in my cerebellum discovered (benign) and that was pretty stressful. I'm slowly getting better, but I'm going to discuss it further with my neurosurgeon because my GI said he agrees with me.
