Hi, I'd vaguely noticed some pain in my right breast but when I had my evening shower 10 mins ago I found that the pain is where there is a reddish swelling, just on the right-hand underside of my nipple on my right breast. I'm really worried and will go to the walk-in surgery in the morning, but is there anyone who can reassure me in the meantime? I feel quite sick and would be so grateful for some advice.
