Breast lump

So I went to the doctor about a month ago with a breast lump, my boob feels hard and rigid and doesn't move as freely as the other. My doctor referred me for an emergency appointment at the breast clinic for scans etc, which is finally next week.

But I'm getting paranoid waiting now as my boob hurts more than before and is swollen, it's a bigger bra size to the other breast.

Other symptoms include itchy boobs and warmth where lump is.

Has anyone had similar symptoms and what happened? Could it be an infection? I don't bf, not pregnant and haven't given birth recently.

Save me from Google pls! TIA
