Hi Jane,
I had radiotherapy back in 2011 so had a long time of getting used to all that came from that. So I know exactly the pain you are talking about under the breast and I get it like across the ribs. My breast became very hard and with another major lumpectomy in 2015 the breast was just sore all the time 'useless in the end' BUT This is what I realised soon after the symptoms I used to get is actual cramping as my pain was never constant but would appear and disappear always bizarre but so painful!! I am wondering as you said youve had it all investigated and I am not surprised they didnt find anything to be honest as there are alot of residual side effects from Radiation. I also have severe burn scarring in my armpit and the left side of the breast. I honestly have never worried too much about it, as for me I know that is what my pain is. After Chemo in 2015 it further compounded it as Chemo shrinks the sheath over your muscles causing cramping throughout the body something I suffer with all the time. A good Exercise Physiologist has been fantastic and has been teaching me stretching techniques which help ALOT!!! Hope you get to the bottom of it and wonder if this resonates for you?
Hugs Melinda xo
