Hi and welocme to HCM.
There are various causes of such lesions, but it sounds to me like this could be hernia, diastasis recti
or some subcutaneous benign tumors (lipoma
, ). You should do ultrasound
with needle aspiration test first to find exact cause, but if this is such enlarged it must be surgically managed, especially if this is hernia which can have serious complications. there is a possibility of having local or regional anasthaesia so you shouldnt be worried about happening all those things again.
Wish you good health.
