Hi, Welcome to Health care magic forum.
As the surgery is an emergency surgery, means the cyst in a serius condition, so it has ruptured and spill along the
peritoneum, caused
peritonitis.
The present pain could be due to the gastric irritation,due to the tablets of the surgery, irritant foods, or alcohol etc.
I usually prescribe to my patient with such symptoms
omeprazole,
domperidone, and anaesthetic
antacid gel.
Wishing for a quick and complete recovery.Thank you.
