How long does it take for a vagina hymen to heal after being delowered?

Not sealing back: Normally, once the hymen is torn, it does not heal-back. Often, a woman does not even know/feel the hymen is being torn. Simple hygiene activities such as use of tampon can tear it and it causes no pain. It is a thin membrane and once torn, it will remain so. If you are experiencing much pain or are very concerned, consult doc. Good luck.
