1st BA in 2014 (botched) revision done 2016 including repair of chest muscle and pockets. 2yrs had no issues at all now every few days my nipples are going dark purple to black and tingle like pins and needles. Pinching and rolling them gently a for a few mins they go back to normal but quite worried my surgeon works for another company now so can’t contact please help. my gp has no clue and can’t contact my surgeon.
