Possible seroma?

So I've posted on here a bit lately about my LBL. I'm about 3 weeks out. Earlier this week I was wondering if my tummy could have been pulled tighter because I had these lumps. Then I thought maybe this was fat I couldn't see bc I didn't get any lipo? Now, and I'm not trying to be a hypochondriac, but I'm wondering if it might actually be a seroma.

I tried Googling the symptoms, but it was hard to find. Can anyone share how I'd know if it was a seroma? Do they hurt? Are they hard or squishy? I'd like to avoid calling my surgeon without at least a little justification for it being a seroma, but I will certainly call if need be.

I was told by a PS on this board that it wou.d have a waterbed like quality. You can push on one side and the fluid would move to another. Also, my surgeon told me that my abdo would be the same size day and night.

Here is my experience with seroma after my TT in April: http://www.healthcentral.com/obesity/c/276918/160778/bariatr ic-life-tells-tummy

I just got one removed and my belly was super swollen like I was pregnant.

But how did you know if it was just swelling from the procedure, vs a seroma?

Mine grew till it was large and very fluid like and produced tha****erbed effect. You could tap one side and see it ripple over to other side of stomach. It also stretched the skin and was overhanging my incision line. It definitely was not firm, but at first when it was small, it just seemed like swelling. Definitely get it checked out.
