I have been throwing up between 10 and 20 times a day for the past two months. Sometimes it is a lot, sometimes a little and is of different consistencies. I am never nauseas and typically feel ok except for getting dehydrated a lot. I have had many gastro intestinal tests done, and nothing has shown up, including ultrasounds, cat-scans, gallbladder tests, EGDs and a few other tests. They then thought it might be something neurological but nothing showed up on the MRI or MRA and the neurologist I saw didn't seem to think it was related....I am frustrated and tired of this and don't know where to go next. I just wanted to know if anyone had any ideas or insight.
