Hello, And Yes. On Tuesday, I Had Severe Pain/burning Underneath

Hello, and yes. On Tuesday, I had severe pain/burning underneath my breasts at the point where the ribs meet (the upside down v-portion). I only assumed that it was indigestion. I drank apple cider vinegar in hopes that it would help. The burning has gone, but now, I feel much pressure in that area (VERY uncomfortable). I am almost thinking of the emergency room at this point. Any ideas? Kym
