Hi, Shelley. I started taking ACV about a week ago. I think it is really helping my poor digestion. I took it this morning and all day, off and on, I have had this strange pain under my ribs, all the way around to the back on the bra line. I have not drank any alcohol for about 10 years or so because I do not like the taste and it always caused a similar pain to this. This happened once last week when taking ACV but the pain subsided after about an hour. Ever heard of this?
