Fluid under left nipple 4 weeks after gyno surgery.

Hello Doctors, 4 Weeks post surgery and the fluid build up beneath my left nipple hasn't reduced. My surgeon said there is no point in getting it removed since the body has to learn to remove it by itself. It will only be a short term fix getting it removed he said. I would love to get a second opinion on this because I read it can hinder recovery or turn into hard scar tissue. My left side is still almost completely numb and my right is perfectly fine by now (actually very sensitive).
