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
, and anaesthetic antacid
Wishing for a quick and complete recovery.Thank you.
