Hello I had a right mastectomy many years ago with a flap reconstruction. If I lean forward for any chore or activity, packing for example, I get severe muscle pain under my shoulder blade along the scar. This pain prevents me from sleeping and is debilitating.  I have had a mammogram and no cancer was present. GP says it's possibly trapped nerves but wasn't all that helpful. I wonder if this is a common problem?  Any advice or suggestions welcome. Thanks
