I have a Parasomal hernia. I was never told about this happening.
I understand it is quite common and mine is small by some standards I am sure.
I suspect, but I wonder how large it could get. I ware a belt every day but take it off at bed time as Gravity is less. It recesses when I have the belt on. I'm a heathy and very active 74 year old and was operated on 4 years ago. The hernia appeared in the first year and so far has not grown too much.
