What would happen if you swallowed a little spring of a pen?

If you swallow a small spring from a pen, it could pose a risk of choking or causing an obstruction in your digestive tract. While the spring might eventually pass through your system, it could potentially cause irritation or injury to the lining of the esophagus or intestines. It's advisable to seek medical attention if you experience any discomfort or difficulty swallowing after ingestion. Always consult a healthcare professional for personalized advice in such situations.
