Sounds like incisional pain.... Is the site red or swollen?
No it's not it all feels inside not outside pain it just kind of radiates
You need to report this to the surgeon. You have a post-op visit coming up? If not, make an appointment and let him check you. Hernia, infection, abscess, adhesions, suture that isn't being absorbed as it should, or even a surgical foreign body from something having been left behind are all possibilities.
I would like to know what you found out about the belly pain and stinging. I am one week post op and having the same feeling.
