I've been experiencing many stomach issues when it come to drinking coffee, eating leafy foods, or eating spicy food. I was told that i had a mild case of Gastritis and that it should go away over time. Ive been dealing with this problem for over a year it sprung up out of no where. Not only do I experience shaking as it has come along I get hot flashes, muscle weakness, sinuses and eyes feel swollen. I have been tested for many thing blood sugar, food allergies, kidneys, liver,heart, lungs, thyroids, everything seems to come back as healthy. Now it effecting my menstrual cycle i've been to the obgyn and they have tested me for everything and it all has come back that I'm clear. Does anyone have any ideas what it could be.
