Most girls do not feel any discomfort during menstruation, but a small number of girls may experience menstrual cramps during menstruation, which may be manifested as cramps and swelling in the lower abdomen, soreness and swelling in the lumbosacral region, or even accompanied by soreness and discomfort in both lower limbs. In some cases, menstrual cramps are more pronounced, affecting the usual work and rest, and even accompanied by gastrointestinal symptoms such as nausea and vomiting, and some patients may suffer from headaches. When these symptoms occur, medication should be used promptly. The most commonly used drugs are non-steroidal anti-inflammatory drugs, such as ibuprofen. The second type of commonly used medication is oral short-acting contraceptives, which can effectively treat dysmenorrhea, as well as regulate the menstrual cycle, reduce menstrual flow, and treat acne.
