Anyone have them or know anything about them? i googled some, but everything said the cause is for the most part unknown and that there isn't really a cure. i did read something that said that they are thought to be caused by a hormonal change. and that HAS to be the case for me..
i got them every once and a while when i was younger, but i've really noticed them in the past few months. and its always right after my period. they hurt SO bad and they always pop up right on the inside of my lips so food hits it every time i chew. they also show up right near the corner of my mouth (on the inside of course) so, once again, when i'm chewing food its constantly irritated. i did get "magic mouthwash" (which is a prescription) from a doctor when i was younger, but it hasn't been helping AT ALL. they are getting worse (i just got 2 in one day.. the last day of my period was sunday) and they are so sore, and getting bigger 
does anyone have any tips or advice on how to treat them?!
