Hi my name is Sam, 39yr, male, i've had Barretts Esophagus for 2 years now, two months ago i suffered a muscle strain in my chest and healed, today I woke up with a sharp localized pain in the middle of my chest i thought it was like acid reflux due to my Barretts but at noon i looked and saw a pink spot where the pain is (near the opening of stomach to the right also near where i had the muscle strain near the right ribs).Please tell me what this is.
