For about 6 months I have had like a constant internal itch at the side of my left breast. I had a trapped nerve (or what they think could be) in the shoulder at the same side a few months before so they thought it could be associated to that. The breast is now very tender, like a PMS feeling but a lot worse. I’m getting a bit worried. Has anyone had anything similar? It feels almost ‘heavy’, but from what I can see it looks and feels ok.
