2. You’re Lacking Support
Gynecologists at the Icahn School of Medicine at Mount Sinai, in New York, point to two rather large sources of breast pain—your girls are lacking adequate support! If you have large, heavy breasts, wearing a properly fitted bra will reduce breast bouncing and movement.
Basically, gravity is not your friend—meaning walking, standing, running, and climbing stairs without proper support will inevitably lead to breast and back pain. So go for a professional bra fitting and spend the money on an appropriately fitted bra that reduces bounce while showing proper support for your sisters.
