Great to hear such positive news ihtos! Did Dr Sanders say anything about the condition of the nerve cords beneath the pec minor - the brachial plexus has formed into 3 cords, the lateral, medial and radial (I believe) at that point.
The damage can be pretty mild to severe. If he hasn't, this should be in your surgical report. Don't forget to ask his office for a copy - pretty fascinating, if a bit weird to read all that was done to your unconscious person.

Can't imagine both sides done at once - it's much easier than rib resection, but still plenty painful having both pec major and minor cut! Hope you have adequate post-op meds. Rest up and feel better!
