During exams and high-stress situations, stomach-ache can be a real issue to deal with. To manage it, I've found that practicing relaxation techniques, like deep breathing or meditation, can help calm my nerves and alleviate any pain. Eating light and easily digestible food before the exam can also prevent stomach issues. Additionally, staying hydrated and drinking herbal teas, like chamomile or peppermint, can soothe an upset stomach. Lastly, I always make sure to take breaks while studying and avoid cramming to reduce stress-related stomach-aches.
