5w PO TT w/ MR, no lipo. All healed except for small, dry scab (less than 1/2") in lower/center incision. Approved to resume normal activity but struggling to stand straight. Very tight at the top of plication under breast bone. Skin puckers there when I try to straighten up. No discomfort anywhere else, just very tight/uncomfortable at the top. I sit w perfect posture but when I stand up, my shoulders hunch fwd. I'm so close! What can I do to get that top to stretch & let me stand up straight?
