"Seroma" post-op?

[Raven]

I'm pretty sure that I have a seroma on my left side,
and maybe a little on the right side as well, (under the arm area) where there was lipo done.

There is this big pocket of fluid buildup and I have been doing a little reading on it, and I am getting mixed results.

I think that I did not have my compression garment on tight enough.

Wondering if anyone here has had this happen?
And what did you do to, and how long did it take to resolve?

Thanks,
