An open wound?
I didn't have anything like that. How can you go to work with an open wound?
It's a gap at the height of where my appendix was, the size of a sigaret hole so it's not a huge open wound. Each day, they put some sort of thick thread with disinfectant in it (iso-betadine wick), with a part sticking out to keep the wound open. The wound can't close until everything inside me is properly healed. Given the fact that my appendix was more to the back, it takes some time to properly heal. (wound fluids still has to be able to flow outside my body). They close it off with a bandage so it should be no problem going to work with it.
Perhaps this sounds icky, but it's not painful. (then again, my pain theshold isn't that low but really, it doesn't hurt)
