[|Human|] I frequently get short sharp stabbing chest pain in my left chest area that I cant pin point. two years ago I saw a cardiologist and had a stress test and echo cardiogram, the only thing that was found, which I already knew was that I have an enlarged septum and I have a functional heart murmer. the doctor said he didnt find anything wrong with me that was causing my chest pain. do i need to get re tested or get a second opinion and can you tell me what is causing this
[|AI|]  Hello. Thank you for contacting Chat Doctor. Sharp, stabbing chest pains, that are localized in a certain small area on the chest can be caused by inflammations of inner chest linings, such as pericardium (the sac around the heart) and pleura (the lining of lungs). Also, this could be a musculoskeletal origin of pain. However, I would recommend that you perform an echocardiogram and a stress test, since it has been two years since your last consult. I hope I was helpful. Take care
