Welcome to health care magic!
I have gone through your question. In my practice I have witnessed few pt. developing such problems after gall bladder surgery
. It idoes not appear to be a very serious condition.
It is not uncommon for stitch sites to hurt for some time but they usually start healing after a week or so.
One can have itch or redness
and some swelling around the cut but you seem to have an infection at that site as evident by-
1. sharp consistent pain at that point
2. started running fever
3. it also hurts when you take a deep breath
4. it is red and swollen
Had I been at your place I'd give my doctor another visit and get it checked just to be on the safer side.
I hope this will be of help to you. Wish you a speedy recovery
Please feel free to ask if you have any more questions.
