The aching associated with menstrual cramps is similar to that felt by runners or weightlifters who have worked out too long or too hard early in the season, and is due to this lack of oxygen supplied to the muscles. With the onset of the menstrual flow the prostaglandin is discharged, which explains why the painful symptoms associated with dysmenorrhea tend to dissipate after the first few days of the period. Medical researchers believe that significant prostaglandin production occurs once a young woman begins to ovulate. For some, the first few years of menstruation occur without the release of an egg from the ovaries, and there appears to be a connection between ovulation and the triggering of prostaglandin production. Heat methods, such as hot baths, applying heat to the cramped area, or simple massage will sometimes help promote blood flow to the muscles and relax spasms.
Exercise is an effective method of treatment.
Try to continue any exercise routine that you're used to. Going for a run, swimming, or taking an aerobics class will increase blood circulation and relax your abdominal muscles. If these methods bring little relief, you can try some of the other products available. You can make an appointment to see a physician or nurse in the Women's health clinic to discuss what product would be most effective for you. Follow the directions carefully for any medications that you use.
