What does PMSing mean and stand for?

PMS is caused by a change in hormones. It usually begins before the period starts, and sometimes continues during the course of the period. PMS can include any number of these symptoms:

*  mood swings
* irritability
* depression
* anxiety
* angry outbursts
* confusion or fuzzy thinking
* tearfulness
* fatigue
* insomnia
* changes in libido
* overeating
* cravings, especially for salty or sweet foods
* alcohol intolerance
* acne
* hives
* abdominal and pelvic cramps
* bloating
* weight gain
* headaches
* menstrual migraines
* breast swelling and pain
* edema (visible swelling, particularly in the hands, feet and legs)
* asthma
* sinus problems
* sore throat
* worsening of chronic conditions like arthritis and ulcers
* difficulty with coordination, being more prone to accidents
* dizziness, decreased balance
* heart pounding (palpitation)
* nausea
* fainting
* urinary problems

Some women experience a lot of these symptoms, while some have no symptoms at all. With me, I get headaches, cramps, irritability, a few pimples here and there, and food cravings.
