Some patients have very severe menstrual cramps, but they have not undergone any examination to rule out endometriosis, ovarian tumors or adenomyosis, etc. Long-term overdose of painkillers can have significant side effects, such as increasing the chance of stomach ulcers, affecting liver and kidney function, lowering white blood cells, and may produce dependence and even cover up the condition. Therefore, it is recommended that patients with severe menstrual pain must go to the hospital for examination to find out the cause of menstrual pain before symptomatic treatment. Some women experience mild menstrual cramps during their menstrual period, which can be relieved gradually after keeping the abdomen warm, taking more rest, abstaining from cold food or drinking ginger water. However, some women with simple dysmenorrhea very serious, even affecting their life and work, can take painkilling drugs for treatment, and patients can also take Chinese herbal medicines for pain relief, such as Yuanhu pain relief tablets.
