Bruised feeling breast?

Hi
I’m an exclusive pumper and am almost 10 months PP I’ve had small clogs before that have felt warm or sore and have been a small bead like lump. I switch from electric to manual pump and it usually gets it out

For about 3-4 days now I’ve had a bruised feeling in the side of my muscle? Under the arm and around the side of the breast area. Somewhat on both sides but mostly my right

I also carry my baby on that side a lot
Supply is the same no lumps I have felt run down but we’ve all recently had colds so

Any ideas ???
