Lump, tenderness, slight changes

Hi 

so just over a week ago I started to feel a different feeling in my left breast, shoulder and color bone As a women we all know how it feels to have soar tender breasts especially around our time of the month but this was a different tender feeling I hadn't felt before and it left me feeling a bit uneased I left it just assuming it is just hormonal but then noticed the skin above my left nipple was pulling up and shrivelled And my left nipple was one minute erect then the next it was going in deeper than it had before and then reverting back to normal it was happening on and off i wasnt sure if i could feel any lumps or not so i contacted my GP who requested i come in for an examination where she felt a lump in my left breast and said that the skin around the armpit on the left side was different to the right it looked slightly more swelled. she done an emergency refferal and i had a call today to go in and see a consultant next week. 

 

im really scared, anxious and have a horrible feeling i cant stop worrying thinking the worse or what to expect.
