How can you relieve cramps and backaches while on your period?

Cramps and backaches: Your symptoms can be relieved with a number of medications that are anitprostaglandins (such a motrin, anaprox, (naproxen) or asa). The cramping is due to prostaglandins released from the uterine tissue, and your backache is probably due to the uterus resting on your back and irritating the back muscles. Both symptoms should be helped by medication.
