I had this same surgery. It is laproscopic with 3 holes. Like you said, the actual incision sites heal quickly but the pain remained for a while, especially on the left hand site where there was lots of internal bruising. It hurt most when I moved in certain ways, especially getting up from a seated position.
I wouldn't do any exercise until you are totally healed because you will only delay the healing process.
It will seem like it is taking forever but will heal very suddenly, very quickly. It won't be gradual, suddenly over the matter of a few days it will go....if you're anything like me anyway.
Get well soon.
