It is not recommended to eat spicy food after New Crown vaccination. Spicy and stimulating food can promote blood circulation, make capillaries dilate, and increase the permeability of blood vessels, thus the vascular exudation at the local injection site will increase, and redness, swelling, hard nodes and pain may appear. And if local adverse reactions occur after the New Crown vaccine itself, after eating spicy food, the local adverse reactions may also be aggravated, and local rash, blisters, and itching may appear. If scratched with hands, the rash may break out and cause local abscess in serious cases. In addition, spicy things can stimulate the mucous membrane of the gastrointestinal tract, and excessive consumption can cause abdominal pain and diarrhea. The above-mentioned gastrointestinal symptoms can also occur after the New Crown vaccine, which can easily lead to aggravation of gastrointestinal symptoms or confusion between vaccine reactions or food causes, which may cause certain misdiagnosis. Therefore, it is not recommended to eat spicy food after the New Crown vaccine, and it is recommended to choose a light and easily digestible diet. It is also necessary to avoid foods that can cause allergies, such as mangoes, pineapples, shrimps, shellfish, etc. Drink plenty of water and try not to drink cold drinks, coffee, tea and various kinds of alcohol. Take proper rest, avoid strenuous exercise, and pay attention to keeping the injection site dry and hygienic to avoid infection.
