Well I have had endoscopy and colonoscopy, ultrasound, nuclear empty stomach test as well as the nuclear gallbladder test. However the empty stomach test shows that it takes a long time for me to empty the contents in the stomach. Except that everything is ok. Also I feel nauseous sometimes. Yup I have kidney stone too. There was one stone that got stuck in the urethra three weeks ago. I pissed one out after the third day but afterward when I pee I do not feel normal there seems to take a while for me to start and the stream of urine is pretty week and the color of the urine becomes clear and pale. There is no UTI after the urinalysis or urine test. On top of that when I start urinating I feel that the urine seems to stop at the opening before it comes out and drips. I have also had the autonomous test cuz my heart rate is pretty high. When resting, it is 80 to 99 or sometimes over 100. But when I eat or walk it could go up to 120, which is scary. I feel heart pounding when that happens.
