Hello, my name is Linda and I experience chest pain occasionally throughout the day, but have felt it every night for about a month in a half. It s hard to take deep breaths, it feels like I can t sufficient oxygen to my lungs. The chest pain feels like pressure against me and occasion sharp pain. I was diagnosed with neurocardiogenic syncope and I don t know if that is related to these event. I am taking florinet to maintain my blood pressure because it tends to be low. Sometimes I feel sharp pain the left side of my chest. I am 5 1, 105lbs, 22 years old. I have a history of fainting and used to have anemia a few years ago. I had a pituitary tumor that is no longer on my pituitary gland. Thank you!
