Work up in the middle of the night with a headache and feeling like throwing up. i went to the restroom and threw up acidic and have dark stool. ?

A doctor has provided 1 answer

Get checked: Dark black melena stools are signs of a stomach bleed. Acid reflux can cause nausea and sour taste in mouth mostly when lying flat, but more concerning is that the stomach ulcer may be bleeding if the dark stools continue.
