Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Seek emergency help for chest pain, severe breathing difficulty, fainting, heavy bleeding, or sudden severe abdominal pain.
A prolapse that is trapped outside and becomes very painful, dark, or dusky also needs emergency assessment.
Contact your surgical team promptly for increasing pain, persistent vomiting, fever, worsening wound redness, pus, difficulty passing urine, or bleeding that is more than a small amount.
Also call if you cannot pass stool or wind as expected, your abdomen is becoming more swollen, or the prolapse returns.
Mild soreness, small spots of blood, and temporary changes in bowel habits may occur during routine recovery.
Follow the discharge instructions for what your facility expects after your specific operation.
