Hey so I'm 23 years old and recently the last 1-2 weeks I've noticed a certain part of my inner left boob (almost where the centre of your bra sits but more onto the boob) feels bruised when I apply pressure. About a month ago I had pain under both my armpits but I had a cold at the time and put it down to swollen lymph nodes. I noticed today a very faint redness on my left boob, it's not raised or itchy, no texture but it's around where the pain is but the pain is only there when I push it, not normally. Also if I lift my arm sometimes I feel a click/pain in my collarbone however I have scoliosis so I've put any shoulder/chest/rib pains down to my spine. I'm just looking for some reassurance as I'm waiting to hear back from my doctor I did an online consultation. Obviously Google makes you think the worst I keep thinking I have inflammatory breast cancer but I'm trying to stay positive! 
 

any advice is hugely appreciated thank you :) x
