Hi, I am 27 yesrs old female and suffering from chest wall pain since 5 years now. 3 years back I was diagnosed with costochondritis through physical examinations. The doctor suggested some anti inflammatory medicines and stretching exercises but nothing helped me. I got xray, MRI, blood test done but nothing comes up in the reports. The cause is unknown till now. I visited many doctors in last 7 years but nothing is helping. Please suggest what should I do?
