last week I woke up in the middle of the night with horrible chest pains and numbness in arm. I called 911, and my throat closed up almost completely. ECG normal, and they think heartburn. All week this week, I have tightness in neck, swollen eye, lips all of a sudden. Swells so much, I look horrible. I take Benedryl, but more of just waiting game. Can this ALL be related to my heartburn/acid reflux?
