Patients with dysmenorrhea usually take painkillers when the pain is severe. Dysmenorrhea is generally treated with painkillers which relieve symptoms but do not address the root cause. If the pain during menstruation does not alleviate, it's not advisable to continually use painkillers. Therefore, before taking painkillers again, it is crucial to undergo relevant examinations to identify the cause of the dysmenorrhea. If the pain is caused by a cold uterus, it is advisable to take medicine that warms the meridians, dispels cold, and relieves pain, and to manage the condition regularly. If the dysmenorrhea is caused by stagnation of Qi and blood stasis, one can take medicine that activates blood circulation, removes blood stasis, and relieves pain before the onset of the next menstruation to properly manage the symptoms. Thus, severe pain can be managed with painkillers. For minor abdominal discomfort, observing the situation generally suffices. If dysmenorrhea gradually worsens, it is essential to visit a hospital for an ultrasound to check for endometriosis. Painkillers can be used during painful episodes of dysmenorrhea, but other times should be managed with appropriate medicines. (Please take medications under the guidance of a physician and do not self-medicate.)
