My menstrual cramps are too severe, what should I do?

Patient's question:

Detailed medical condition and consultation purpose: I have been experiencing menstrual cramps for seven or eight years. The pain starts from the first day of my period to the second day, and it is extremely severe. Almost every time, I sweat profusely, shiver, and vomit. Even drinking brown sugar and ginger decoction doesn't help much. At the age of 18, I had a gynecological examination from the rectum at the hospital, and the doctor said there was nothing wrong. I have also seen traditional Chinese medicine doctors intermittently and taken some blood-activating and resolving stagnation Chinese herbal medicines, but the effect was not very significant. A few months ago, I saw a traditional Chinese medicine doctor again, who said this condition has already become chronic and at least needs to be regulated for half a year. At that time, the doctor prescribed medicine for four days. On the third day of starting the medicine, I don't know if it was the Chinese herbal medicine

Doctor's answer:

Hello:
Has the cause of dysmenorrhea been clearly identified after a gynecological examination? The causes of dysmenorrhea include:
Primary dysmenorrhea is generally believed to be attributed to the following reasons: endometrial shedding (membranous dysmenorrhea), uterine underdevelopment, uterine flexion, cervical stenosis, poor posture and constitutional factors, allergic states, and psychological factors, among others.
　　Secondary dysmenorrhea occurs when pelvic organ abnormalities are detected during bimanual examination. It is often misdiagnosed as primary dysmenorrhea when local abnormal signs are not yet apparent. Therefore, women with dysmenorrhea that begins more than 3 years after menarche should be considered for secondary dysmenorrhea and undergo further examination.
　　The most common cause of secondary dysmenorrhea in young women is endometriosis, which has symptoms very similar to primary dysmenorrhea. If the patient has progressive dysmenorrhea or a family history of endometriosis (with the mother or sister suffering from the condition), laparoscopic examination should be performed early to confirm the diagnosis and undergo conservative surgical treatment to preserve fertility.
　　Additionally, the causes of secondary dysmenorrhea include congenital uterine malformations (including bicornuate uterus, septate uterus, unicornuate uterus, transverse vaginal septum, etc.), pelvic inflammation, adenomyosis, uterine fibroids, uterine polyps, uterine adhesions, cervical stenosis, ovarian cysts, and pelvic congestion syndrome, among others.
　　In addition to dysmenorrhea, elevated body temperature during menstruation should be considered a sign of pelvic inflammation. Approximately 5% of women using intrauterine devices (IUDs) experience dysmenorrhea. If there is no infection, the cause of dysmenorrhea may be the IUD stimulating the endometrium, leading to excessive release of prostaglandins (PGs) and causing overly strong uterine contractions.
