Well, I'm a guy, so I wouldn't know personally. My girlfriend, however, has pains in her back as well when she is on her period. I think it is pretty normal, but if you think something is wrong you should always go and have it checked out.

Back pains during a woman's menstrel cycle are quite normal. However, severe pains should be investigated by a good GYN. If all is normal in that department you could try a good chiropractor. Many women have experienced relief from painful cramps, or a reduction in their severity, by having their spine alligned properly. All the nerves are connected to the spine. If the spine is out of place even a little, it may cause undo discomfort that can be improved. Other treatments include a heating pad, hot baths, and, yoga. But, first and foremost, have your GYN give you a check-up to eliminate other possible causes. Good luck, and remember, it all goes away when you reach my age. :))

Back pain is a symptom. Pain arising from other organs may be felt in the back. This is called referred pain. Many intra-abdominal disorders-such as appendicitis, aneurysms, kidney diseases, bladder infections, pelvic infections, and ovarian disorders, among others-can cause pain referred to the back. http://www.backpainadvice.org

Menstrual back pain can be a monthly occurrence for many women. Dysmenorrhea is the medical term for the muscular cramps that can cause abdominal and back pain during the menstrual cycle. Muscular back pain caused by menstruation is not serious and will go away in a few days. However, during a women’s menstruation, back pain can be a yet another very uncomfortable symptom to endure. Besides pain in the lower back and upper thighs, menstrual cramps can produce many other symptoms. Headaches, dizziness, fatigue, nausea, digestive problems and emotional sensitivity are all common side effects. Some women display sweeping mood changes and rapidly changing emotional states. Causes of Menstrual Back Pain Back muscle pain can be caused by the same hormonal changes that cause abdominal cramping during the period. Chemicals called prostaglandins are responsible for promoting uterine contractions during menstruation. These same chemicals can cause havoc throughout the body and especially in the lower back muscles. This condition can be much worse in women who also suffer from hormonally induced pre-menstrual syndrome. The chemistry occurring in her body can cause physical and emotional symptoms for up to 2 weeks every month! Treatment for Back Pain During Your Period There are prescription drugs and hormonal therapies available to help women with severe painful symptoms. However, I would recommend avoiding these unless your symptoms are out of control. The side effects and health risks are just too great to justify their use for mild pain symptoms during menstruation. Try some OTC pain relief instead. Midol or Advil are indicated as popular remedies for cramping and pain. Believe it or not, one of the best treatments is WATER. Much of the discomfort that women suffer during their period comes from dehydration. This is exacerbated by some women losing their appetite for food and drink during their menstrual time. Make sure to drink lots of water and you might be surprised at the positive results you will experience. Recommendation for Menstrual Back Pain I understand that this monthly ordeal can be uncomfortable and annoying. In the majority of cases, the pain is not serious. Just relax and let your body do what it does naturally. Take time for yourself to unwind and do something you enjoy. This positive mental state will help to balance out the physical changes and discomfort. If your symptoms are severe, meet with your doctor or gynecologist to discuss treatment options, but be sure to discuss any downside to a recommended therapy modality.
