Primary dysmenorrhea is the most common kind of period pain. It is period pain that is not caused by another condition. The cause is usually having too many prostaglandins, which are chemicals that your uterus makes. These chemicals make the muscles of your uterus tighten and relax, and this causes the cramps.
Food poisoning also can cause cramps but but does not make Actipatch the Tx for food poisoning. In the end it Doesn't matter. BIEL needs a partner to start selling ActiPatches. Lots of them.
