Ok, I can tacle all of this:
1. it may be 'fixed' but the tissue of the valve/stoma may have stretched out due to the bend or curve that you previously had and that may cause a turtle-neck effect meaning that you have an extra-long valve now and some of it just sticks out...no leakage or air or stuff other than post-intubation (a couple of drops is normal) then you are fine...
2. Stinging or burning may just be temporary...post op trauma to the zone...you don't say where it stings or burns. Is it the part that sticks out or is it deep down inside?
3. Mucus is indicative of irritation. The whole zone got a whomp of irritation done to it and it needs time to settle down and heal...as long as there is a bit of inflammation (and its new friend, the mesh, is a stranger for the moment and it may just be irritated about him moving in) you are going to get more mucus.
Give it time to settle down before you decide if this is a problem or not...I always say 2 months just to be sure.
For now, relax and heal. Give things time to settle in. No hurry...
By the way, the amount of mucus that you describe is my normal...just saying. I change pads about 6xs/day plus I wear a 1/2 mini pad glued to the inside of my clothing for more protection...and I still have a few drops come through...I got used to it and deal with it normally...
