Found out I have slipping rib. This explains all the pain I have been feeling for months!
@kkmamax3, they say it can be from trauma, injury, surgery, but they still don’t really understand.
@kkmamax3, Slipping rib syndrome occurs when the cartilage on a person's lower ribs slips and moves, leading to pain in their chest or upper abdomen.
@kkmamax3, thank you!
