Played badminton with normal bra (non sports) - afraid of tissue/ligament tearing esp on right breast as i'm r/handed. no pain felt. does this repair?

"ligament tear": Ligaments can be repaired, but it is unlikely that the type of bra would affect the tearing of ligaments. The breast movement with strenuous activity can stretch tissue in the breast so that the breast falls lower on the chest when good support is lacking. The "repair" of that is difficult and not always successful. Sports bras are preferable to avoid this.
