Taking painkillers every time you have your period will relieve your menstrual cramps at that time, but you will still have pain the next time you have your period, so it is better to find out the cause of menstrual cramps, such as ultrasound to find out whether the uterus is developing normally or not, and to find out whether there is a narrowing of the cervical canal that causes the menstrual blood to flow poorly, which leads to the symptoms of menstrual cramps. In addition, if there is pelvic inflammatory disease can also cause dysmenorrhea, endometriosis will appear progressive aggravation of dysmenorrhea, and may also lead to infertility, so find out the cause of the disease and then give the treatment to completely alleviate the symptoms of dysmenorrhea. If you take painkillers regularly to relieve pain, it may relieve the symptoms clinically, but it may also cause other effects, such as a drop in white blood cells and a decrease in body resistance.
