OK quick update.
I need to see the practice nurse every day at the moment to apply a special anti-bacterial dressing. None of the medical professionals seem to think the wound is actually infected and this is to be on the safe side really.
The wound is still discharging quite a bit (i guess a couple of tablespoons of liquid per day). It isn't particularly painful but I am bored of it not healing properly. Still it is only 12 days since the surgery hopefully it will heal soon.
The actual flap of skin sown over the fissure seems to be healing fine. I am having problems with the site that the doctor cut the skin flap from.
I am recording this because hopefully it will help someone else who is going through similar surgery one day.
One other thing is that as part if the op the doctor also gave me botox. This means that when I need to go to the toilet it is very urgent! I have about 10 secs to get to the toilet before things become super urgent! No accidents yet but it feels like there could be! Has anyone else experienced similar with botox?
