HUGGGGGGGGGGGGSSS to have an open RNY procedure mate.
You're not a lone sweetie. I did mine open last April 18th.
I know it sores like hell, but trust me this will fade away on the 4th week. give yourself sometime maybe untill 5th-6th week and you'll be very impressed about the results of your body transformation. Of course everybody is different, maybe you're body will take less healing time than mine.
I had few complications coz the Doc had to make a small opening in my 15 cm wound (1 cm) to let the discharge to leek out and help the healing process. It was yucki and uughhh but it took a week to get everything closed.
Hang in there you'll be very impressed honey. Please don't hesitate to drop me a PM or a post on the board
