Freeze some pads soaked with witchhazel this is meant to be wonderful a friend did this it helped with the healing and the swelling as well. Aside from everything else suggested here its just part and parcel of the healing process. Internally there is nothing really that you can do to minimise the scarring and TBH I don't think externally you will be seeing much unless you get downthere with a mirror Just keep and eye on the wound though (with a mirror) so you can see if you happen to get an infection at all.
