Fluid build up after gynecomastia surgery?

On sunday last week, I have undergone a gynecomastia surgery on one side without lipo. The next day I noticed fluid buildup in the area. I went to see the surgeon, but he said that its normal and that my body would reabsorb it. There is enough amount of fluid to make a noise when I press on it but not enough to make the “waterbed” effect”. I went again yesterday, the surgeon tried to aspirate it but nothing came out. He said that the fluid was still thick and that I should wait for 2 weeks.
