Hi thanks for writing here.It seems you have got flushing
.Since your flushing is related to eating it is possible that you have got food allergy
.Eating foods that trigger an allergic reaction
can cause facial flushing almost immediately after you finish eating. Food allergies
cause a systematic reaction in the body that releases various chemicals to defend the body, which can cause a decrease in blood pressure, leading to flushing of the skin. Common foods that cause an allergic reaction include wheat, eggs, milk, fish, soy, tree nuts, strawberries, tomatoes, pineapple and peanuts. A severe reaction to a food can cause life-threatening symptoms.So it will be better you consult an allergy specalist and take treatment accordingly.Take care.
