Hi Teresa,
Yes, pain continues...and it varies in it's intensity for no apparent reason. Sometimes I would go for days or weeks with no pain, then would experience several days with pain. I just figured it was the breast tissue continuing to "wake up" and heal after having been fried by radiation. I've spoken with many others who also have had varied but ongoing experiences with pain.
It does diminish over time...be patient. Perhaps a heating pad or soft massage would help.
