Hi there ~
It is not uncommon to have this feeling of hotness or feeling flush after a meal, particularly a spicy or a heavy or an unusually warm one. Everyone's physiology is different. However, if you feel that it is unusual for you and that it is causing you discomfort in any and every situation, I would recommend that you see an endocrinologist
first since it could be hormonal
. If you have ruled this out, an unusual form of anxiety
disorder may be the case. However, you would need to consult a psychiatrist
for a detailed evaluation. I hope this helps. Take care and have a safe day !
