Sorry to post again about my health.
Last few days I've had a very itchy breast, so much so while out I've had to go to the bathroom to itch it. My nipple then got very sore to even brush against it, although that part hasn't been itchy. Then last night I noticed a lump under my areola and it was very red. Now this morning I have checked it again and the redness has spread about a quarter of a way up my breast overnight. I have rung the GP and am waiting to hear from them. I am not breastfeeding and I foolishly googled and am terrified. Has this happened to anyone else and it not been sinister?
