Ive been dealing with pain near my breastbone for about two years now, but its been worse since 2016. The pain happens when Im sitting, lying down, or stretching, and I cant walk much because of it. I also have trouble breathing sometimes, feel fatigued all the time, and get headaches and a sense of nostalgia. Ive had an MRI, ECG, and blood tests for vitamin D, BMD, etc., and all the reports came back normal. The doctors say its costochondritis, but Im still unsure if theres something else going on. Can you help me understand if this diagnosis makes sense, or if I should consider other options?

It sounds like youre dealing with persistent chest pain that has been diagnosed as costochondritis, a condition where the cartilage connecting your ribs to your breastbone becomes inflamed. While your tests are normal, this can still cause significant discomfort. Treatment typically includes anti-inflammatory medications, gentle stretching, and avoiding activities that worsen the pain.
