I never had them until 2007...then it felt like they wouldn't stop...I had them in multiples of 2's and 3's...it didn't take much...I would pluck a weed, get a roast out of the oven or twist sideways...it all seemed to rip something inside of me...I ended having about 7 or 8 repairs done including on my pouch (I ended up with numerous peristoma hernias too)...
Things have calmed down since about 2012...or maybe all of my guts have criss-crossed patchwork of mesh repairs!
Either way, it is a bit better now.
I cannot explain why it started or why it stopped...just that I am thrilled that it has.
