Went out drinking lastnite woke u this morning my chest is killing me n i know i'm not having a heart attack but it feels that way ?

Call 911: Unfortunately, one of the most important features of a heart attack pain, is that it feels like a heart attack. You don't want to wait for this. Call 911 immediately and go to the emergency room!

Reflux: It is not uncommon to experience severe esophageal reflux and even gastritis after drinking alcohol. Both these can cause very uncomfortable substernal ( beneath the breastbone) pain. But you cannot exclude the heart if this persists. If it worsens or persists you should see your doctor.
