What is the most embarrassing disease/medical condition you ever had?

I don’t know what it was, because the doctors couldn’t figure it out, but it was some digestive thing, upper gastrointestinal tract. I constantly felt full, constant heartburn, I couldn’t burp, so air stuck inside of me and made me uncomfortable and dizzy, when I ate it felt like I couldn’t even swallow and that it all stuck inside my throat. It was embarrassing because I never knew what was safe to eat enough – if I ate something wrong, which could be absolutely anything, I started to shake, get dizzy spells, sometimes fainting, sometimes throwing up. I could barely be outside, I felt. It went on for a few days, then disappeared almost fully.
