I am also a patient, male, 22 years old, this is a genetic disease, and I feel that the effect of surgery is definitely not good! I've been going to the gym for almost a year, and I feel good. Although sometimes my heart is very uncomfortable, but much better! I can wear a tight vest now! And it looks natural, the pectoral muscles can already hold up a lot of funnel chest! People with this disease are all thin. My height is 186. Last year before exercise, it was 1 15 kg. I have been exercising now 152 kg! Of course it has something to do with food. Eat beef and egg white every time after fitness! I don't feel inferior outside, and I often play basketball with bare arms in summer. I think as long as the muscles get up, the body will coordinate. Outsiders will look at your muscles and overall proportion, and will not stare at your chest! I wish you happiness, this serious illness can't be cured, so don't have too much psychological pressure! I wish you happy every day!
