Period pain varies from person to person, so there is no definite level to determine. During menstruation, due to the secretion of prostaglandins, the uterine muscles contract and the uterus experiences spasmodic pain. If it is relatively mild there may be a feeling of abdominal cramping, lumbar pain, this is relatively normal, you can pay more attention to rest and observation. If the pain is severe, causing the patient to pale and sweat profusely, or even fainting, then most of the degree level is higher, usually due to organic diseases triggered by dysmenorrhea. Therefore, women should avoid cold stimulation during menstruation to reduce the degree of dysmenorrhea, and if the degree of dysmenorrhea is severe, it is recommended to go to the hospital in time to consult a doctor to clearly check whether there is an organic disease.
