Hello everyone, three days ago I noticed two red circles around the size of a 5 pence piece each had appeared beside my nipple on my right breast. I also have another below my nipple on my left breast however it is not as bright as these two. There is no pain, and no itchyness, they are flat and feel just like my skin however they have stayed bright red for three days now and do not seem to be going away. My nipples also seem like they have gotten larger and slightly darker lately. I can not feel any lumps, however I have been getting some pains in my right armpit and my breasts lately too. 
 

Should I book an emergency GP appointment to have this looked at? I feel like it is probably nothing especially since I am only 22, however, I am not pregnant or breastfeeding and have never had anything like this before. My mother has also had breast cancer in the past so of course, naturally, this makes me worry a little as I have heard about IBC. Any help would be most appreciated.
