I am 6 weeks out from part 1 of a 2 part jpouch process, meaning that i have the major abdomen incision, but it's not yet been reopened! My surgeon was excellent and i was fit and healthy (and relatively young) before surgery. My bandages came off after 4 days with no need for any more.
That said my incision Mark is still a little numb (a bit of nerve damage as i have no feeling in the surrounding area), and my core is still weak and sore (I'm not ready for sit ups yet!)
There's one patch in the very centre of the scar tissue that occasional weaps a little! I have it a gentle squeeze yesterday and it did drain a bit of puss, but i think that's because I've been playing with it and infected myself! I don't think drainage is much to worry about as long as its not much and your not in pain, but I'd also suggest it probably should be drying up by now.
I'd keep it clean and aired and use antiseptic creams overnight and basically leave it alone!
As long s the drainage is watery and doesn't smell or change i think you will be ok! Worth mentioning to your doctor next time you see him though
I'm not a doctor or anything, just my thoughts
