Shooting pains in breast some time after surgery

I still get pains in my side near the breast five years after surgery.  My GP thought perhaps scar tissue impinging on a nerve and my oncologist went along with that diagnosis.  I’ve stopped worrying about it now but I’ll turn a certain way and suddenly, it takes my breath away.  It only lasts for a few seconds fortunately and I just live with it now.  Another of the “fun things” we have to cope with post BC.
