I have a lump in my left breast that goes away on my period but comes back almost immediately after it ends. It's painful to the touch, kind of like when you touch a nasty bruise. It's a decent size and can move around as well. I first noticed it back in May when my arm bumped into it, but I had noticed a lump in the past but never thought much of it. I am pretty confident it’s nothing to be concerned about, but I just wanted to ask others.
