Every time i eat i feel sick afterwards. Not straight away though.... I usually try to go for a walk an hour or two after eating but as soon as I get in the car to drive to the lake I feeL ill... any movement travelling or walking I feel ill like I need to either throw up or poo (sometimes I can do neither. Walking makes it worse and after some time walking I end up with really soft poo. The nausea feels like when you have diarrhea and there s that feeling in your stomach like you need to go and can t stop it. I don t know what s wrong with me and I have to wait two weeks for tests.
