Very similar thing been happening to me, been in and out of doctors for 6 months now. Hope you find some answers. Mine will randomly flare up then be fine for a couple weeks.

I experience this too! Almost every time I get up from anything I get that feeling too, like getting up from my bed I’ll lose my vision a bit and feel faint and need a moment, I think it has to do with my iron but I’m not sure. You’re not alone!💗

A lot of things can cause the symtoms you're describing. I recommend seeing an ear nose and throat doctor to rule out any inner ear issues. It could be dehydration, thyroid issues, or anemia. Or! It could very well be dysautonomia, the family POTS belongs to. That's what I have and I feel similarly. If you do see a neurologist, you could ask about it but most doctors are unaware or severely undereducated on dysautonomia The fact that your symptoms worsen after eating is normal, please don't worry! Digestion takes a lot of blood flow away from the brain and to the stomach so if you have circulatory issues this can cause some Bad Feelings for a few hours - happens to me regularly

this happens to me too omg!
