Period pain, also known as menstrual pain, is a painful cramping sensation felt in the lower abdomen either before or during your period.
However, to understand why we get these painful symptoms, we first need to look at what changes happen in the body during our cycle.
During your menstrual cycle, your body releases two hormones – oestrogen and progesterone. These send chemical messages to release an egg and thicken the lining of your uterus in case you become pregnant.
However, unless you do become pregnant,this egg won’t be fertilised. And when your body realises this is the case, it’ll release chemicals known as prostaglandins to shed the uterus lining through your vagina.2
But this shedding doesn’t happen on its own. To move the process along, the muscles in your uterus will start to involuntarily contract. And it’s these contractions that cause the cramping sensation you’ll often experience during your period.2
This pain can be felt in different ways, ranging from a dull ache to cramping and sharper pains. You’ll also most commonly feel it in your lower abdomen, but it can spread throughout your body – from your stomach to your lower back, groin, and thighs.3
