Final answer:
Lower back pain is often due to uterine contractions that can radiate to the back during menstruation. Methods for relief include warm baths, heating pads, exercise, and ibuprofen. Severe pain should be addressed by a doctor.
Step-by-step explanation:
Lower back pain during your period is a common symptom for many women and is often due to uterine cramping. These cramps can radiate to the lower back, causing discomfort. The pain and cramps occur because the uterus contracts to help expel its lining during menstruation. This process can sometimes affect nearby muscles and nerves, resulting in back pain. Menstrual pain relief methods, such as taking warm baths, using heating pads, engaging in exercise, or taking anti-inflammatory medications like ibuprofen, can help alleviate this discomfort. If the pain is severely incapacitating, it's important to consult with a doctor who can prescribe stronger medication or investigate other potential causes.
