I have pain in both breasts mostly left breast, my right shoulder blade, centre of upper back and down into my flank. It comes on in the evening whilst I am resting and feels like a deep ache and stabbing pain. It gets really bad and I have sometimes cried with the pain. This is not me as I am used to pain, having had all sorts of surgeries in the past. I don’t exercise so haven’t done anything that could cause muscular pain and it comes on me when resting. 
I have had the back shoulder and flank pain for about 3-4 months now and just put up with it as I had surgery on my neck and shoulder in the past and thought maybe it’s connected. 
However this pain has been unbearable at times, so I went to see my orthopaedic surgeon who did the shoulder op, she said given its position and how I described it, it is definitely not linked to the shoulder and has referred me to a pain management team and also back to my neck consultant. However I now have breast pain which feels quite painful, there is a slight redness and some little red marks on my left breast and if I touch my breast it’s sore. I was born with inverted nipples so have no indicator there to go on. 
any useful comments please would be much appreciated x
