I Had third degree tearing inside and out.
It killed to urinate afterwards and I only found it bearable by pouring a jug or water "down there" at the same time as i went. My tear was quite big though and in a bad spot.
it healed after about 5 weeks, though my stitches didnt dissolve like they said they would. I had to get them removed ! OUch ! When the swelling goes down a bit im sure you will have a look , dont be freaked out it will all heal well in time ....
