I have been having problems with tightness in my neck and throat. It starts randomly and can last for hours. It causes me to gag. It happens pretty much everyday. I was having stomach problems for about a year, so I went to a primary care physician and a gastroenterologist. I was found to have Hashimoto's syndrome. My gastroenterologist gave me an upper gi endoscopy where all the results came back normal. I just feel very frustrated and do know what else to do because this problem doesn't seem to go away
