[|Human|] Ive been having a tightness in my chest lately. Im a smoker and sometimes its hard to take a deep breath. What should I do and what could be the cause? Theres no real pain and Im experiencing no real difficultly breathing. Just a tightness in my chest slightly superior to the navel extending upward to a few inches inferior to the nipples. Ive been diagnosed with GAD in the passed but have no previous trouble in this area. So...what could be the culprit
[|AI|]  Chest pain can have many possible causes and generally should prompt a medical evaluation to rule out serious causes. Important causes to rule out given your smoking history include heart disease, emphysema and asthma. The initial work up includes a medical history performed by a doctor, an electrocardiogram, and a chest x-ray. Generalized anxiety disorder makes you more prone to panic attacks which can present with chest pain like this, but the other more serious causes should be ruled out first before blaming it on anxiety. I hope you get this figured out soon.
