Women with menstrual pain can generally find relief by placing alcohol-soaked cotton balls in their ears. The alcohol evaporates inside the ear canal, and the nerves send signals to the brain indicating numbness in the ear. Upon receiving these signals, the brain interprets them as localized numbness and stops processing pain signals. Additionally, it's important to maintain hormonal balance, develop healthy habits, and go to bed early and wake up early. Soaking feet before bedtime and drinking warm milk can help ensure good sleep quality.
