Hi Waldog, I actually had surgery on March 14, 2012 and I was told the pain was air that is trapped since the procedure was laproscopic. But oh my gosh! That pain is crazy pain, I know exactly what you mean, you are not alone and it will fade after about a week, I promise! Just remember it's for a great reason otherwise we would not have even thought of doing this, right?
Good luck and remember it will seem more positive as the days go by. Take Care
