I had something similar to this hun, its where the incisions meet and they will take longer to heal…i still have a small faint yellowish scab under my left nipple and like you at the bottom of my scar…the nurse picked the scab off with tweezers when i saw her last week and she put a dressing on it as it bled a little, she said leave the dressing on for 24 hours which i did, once i took it off it had dried out and it has a faint yellow film over it now…i’m pretty sure its nothing to worry about… Is yours wet at all? Have you spoken to the nurse about this? Don’t forget hun, your still early days and prob still have some healing to do xx
