It’s Just DCIS, the words of the BCN leaving me feeling like a fraud

@Blister
Talk to your GP and perhaps get the 5 visits to a Physio with the view for an assessment and treatment for lymphatic drainage massage.  It sounds like the after affects of surgery.   The BCN has moved on to other patients by the sounds of it!
I suffer pain in the sternum near on 6 years later.  When it starts I head to Physio. 
I presently use my 5 visits for an Exercise Physiologist through a cancer program.
Hope this suggestion is of help!
Take care
