This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Golf ball marker is a round object.
The size is the concern here.
In most cases, this should pass through your intestine without problem.
But in some cases, there is risk of bowel obstruction and also the marker can get lodged in intestine causing perforation of bowel.
Given these small risks, a clinical evaluation is warranted.
The marker can be extracted by endoscopy.
Please go to the nearest bigger hospital ER.
It was my pleasure to help you today.
