Hello, 

On Thursday I noticed a pain in my chest just to the right of my left breast (where your bra would usually sit) I thought nothing of it just maybe where my bra had been digging in! Anyway the next day I noticed it was still quite painful and it had turned a purple/red colour and I noticed a small lump roughly the size of a 2p ish. 
Move to today and it's still there, still red and still quite painful but now my breast feels quite heavy and it's still tender to touch! I'm going to make a doctors appointment tomorrow but I'm going out of my mind with worry! Has anyone else experienced this?
