Thanks for posting your query.
Sometimes tissue dose not heal properly after surgical incision and some tissues may protrude. Post surgical wound complications like wound infection
, wound dehiscence (wound not properly closed),foreign body can impair wound healing
. You should not worry as long as it dose not bother you and cause pain,discharge or any discomfort. However, if you find it uncomfortable then you should visit your doctor to rule out surgical hernia
Avoid physical activities that cause stain or stress
on your abdomen.
Hope it helps.
