Hello, I am 26 years old and I have a stern bone problem, my stern is 10 cm inside my body. I don't have any breathing problems. This problem with my stern bone dates from more than 12 years, when i was 13. Does anyone know how my stern bone can be fixed? it is really necessary a surgeon? i have made for more than 10 years recovery gymnastics, but in vain. What advice would u give to me? Thank you!
