 [ Symptoms ] my 12 year old boy has pectus excavatum…should he continue wearing posture brace [ Disease ] hi it seems that using the brace is the cause of pe he may be using it quite regulrly and as the bones are quite soft and mouldable at his age they are getting compressed at chest level he can wear brace intermittently followed by daily chest exercises this will take care of posture as well as pe back exercises and yoga are of immense help for postural problems give him calcium and vitamin d supplements thanks
