Hi! I am on day 5 post-op. I am not sure if my sports bra is to tight? Will it help bring my boobs closer together?Will it do any damage? I sleep in the surgical bra at nite, so that they can breath & not be forced together, but both bras are tight. My ribs feel bruised & they leave marks! Any suggestions on how tight a bra is supposed to be would greatly be appreciated. Also, is it ok to lay completely flat on my back when I sleep?
