Dear madam, usually after laparoscopical surgeries th increased level of air in abdomen can cause shoulder pain, especially the left one because of irritated phrenic nerve
. But skin redness and warmness aren tusualy sign of it. It can be caused by skin infection
or allergy or by joint inflammation
. So you should do inflammatory markers
and shoulder RTG if you are worried about it.
Wish you good health, Dr. Romich
