I’m new to this website and not really sure what to post but I’ve noticed I’ve had a sore right breast for nearly a week now, and it’s starting to get worse as time goes on. I’ve also noticed it’s feeling quite heavy and swollen, especially when I wake up. I know as I’m 19 I’m at low risk but my mum sadly passed away due to breast cancer so I’m just always very anxious. I’ve also had pain in my right chest and a pins and needles feeling go down my arm on a couple of occasions but that comes and goes.

Does anyone have an idea what this could be, or have had a similar thing? 

Any help would be much appreciated, thank you!!:)
