I had the same, like a viscous fluid that just keeps coming out? Mine wasn't infected either but I did get it checked out by a doctor. If you can get your friend to check it regularly or pop off to your GP in the morning. If it smells, the discharge changes or you get a temperature there could be an infection and you'll need seeing asap, so keep a very close eye on it. It does take them all a little while to heal, usually each wound at different rates, the main one that they put the camera in is usually the last to heal x
