Weird Symptom with Histamine intolerance- Have you had this?

I have the strangest symptom with my HI, it is a pulling sensation which is hard to pinpoint but seems to be coming from the lower stomach deep inside. You know when you are driving, and you go through a dip in the road a bit too fast, and you get that slight G-force feeling?

Its like that only constant during flare-ups and very annoying. seems to affect my balance a little as well.

Has anyone else experienced this?
