Is there any connection between the week before your period and having canker sores?

Question

Every month during the week before my period, I have an outbreak of canker sores. I've puzzled my doctors before, but they don't see a connection. I believe they are connected, but I can't see the link.

PS: I've had the outbreaks since I was a kid.

Answer 1

Canker sores, also known as aphthous ulcers, are painful ulcers of the skin lining the mouth and tongue. Canker sores are usually small: about one to two mm long and appear as white, painful, non-contagious, inflammatory lesions. They appear on the soft tissues and folds of the inner cheeks and lips, or the floor of the mouth

Women between the ages of 20 and 40 suffer from painful recurrent canker sores. ... Emotional or physical stress, anxiety, or premenstrual tension .

Approximately 20% of the U.S. population is affected with recurring canker sores, and more women than men get them. Women are more likely to have canker sores during their premenstrual period.

Yeah, you're right.  I do get them all the time including the bruises on my legs during the premenstrual period.
