My routine today has been hot compresses and massaging the ducts towards my nipple. So far, I’ve had some relief. It feels like the lump is smaller and bumping my breast doesn’t hurt nearly as bad. Just wondering if anyone has had a similar situation?

Ya, it's called "budding" and is quite natural when a female is in puberty or a male is growing breasts.  Just look at earlier program pages and almost all of us has had the same problem.
