HELP.....?? about my drain....

OK so twice today my one drain "expanded" on its own when not full?  WOndering if it could be some of the air from the surgery blowing it up.....the top is on tight and its all ok- not really getting a lot of drainage today but that expanding on its own has me a lil concerned---
thanks in advance for any answers--

update now 3 times this has happened-- ????????

I'm thinking that's what it is.....If it really bugs you I would contact your surgeon....it could be that all the excess fluids are gone and the only thing left is the air???

I think this warrants a call to the surgeon.
