Dysmenorrhea to the extent of vomiting is generally a grade 3 pain. Dysmenorrhea is a painful condition in the lower abdomen that occurs around the time of menstruation, which can be cyclical, mainly manifested as abdominal cramps, pain or distension, and may include lumbosacral soreness, or pain in the inner thighs or around the anus, and can be classified as mild, moderate or severe. In addition to vomiting, nausea, diarrhea, fatigue and dizziness may also occur. Severe dysmenorrhea may also lead to deficiency and shock, and it is necessary to go to the hospital immediately. Generally, there are two types of dysmenorrhea: primary and secondary, and in the case of primary dysmenorrhea, most of them are treated with painkilling drugs. However, if the dysmenorrhea is secondary, there is usually an organic lesion of the primary lesion, so it is best to go to the hospital and have the primary lesion removed and then the dysmenorrhea will be relieved.
