So I had a surgery(appendectomy) around 2 years ago.I completely recovered from the surgery after 5 days from it,so it doesn't cause any inconvenience or pain or anything related.

Thankfully,I was in another country when I did the surgery so it is not on my papers.

And I just have a small scar above my belly button...So should I tell them about that when they ask me if I had any surgeries?
