Heyyeveryone. I recently just got out of the hospital. I was born with a 'caved-in' chest. However, only a year ago, I found out a way to fix it. Basically, the surgeon puts me to sleep, and then carefully shoves a concave bar into my side. He then flips the bar, shoving my ribcage outward, fixing the depression. I was in the hospital for a week, with a tube in my chest sucking out fluid, and taking morphine(until I learned me and morphine don't get along well) I watched a few movies, and soon got out. I feel great, and will finally feel comfortable about taking my shirt off.
Here is a link on the condition. My former condition
