Mastopexy vertical scar issue. What can be done to fix this?

I have one breast that appears suspended by the vertical scar, such that it has "2 halves" or two lobes between the areola and the bottom of the breast. The suture is acting as a cord that is too tight. I've pinched and gently pulled it for several months it trying to release the tissue, but have not been successful. What else can be done for this ? Would some type of suction assisted therapy be effective? What other options do I have ?
