Inflamed feeling upper chest/lower throat

Could I have Costco if it doesn’t necessarily hurt to touch? I’ve been having this inflamed feeling in the highlighted area and sometimes it spreads lower or out a bit and sometimes it’s in my lower neck and painful and feels like my throat is swollen. I’ve had an endoscopy and been to an ent. I do get acid reflux but I really don’t know what it could be and it’s driving me crazy.
