How to tell if you damaged breast tissue

I may have over massaged an old clog. I know I know - it’s a no no now. But I’m well beyond the clog and have been on antibiotics for a week already but my breast feels a little firmer than the other one. It’s not painful, just more firm.

Not sure if this is a bad thing? I see my PCP in a few weeks and will ask her about this but has anyone overdone it on a clogged boob before and able to tell me if it had any major adverse effects? The biggest outcome of this was that production plummeted on that side and hasn’t come back but other than that things feel more or less normal outside of the breast feeling firmer than the other saggier and deflated one.
