Gained and Lost Approx. 50lb in Two Years - Tummy Tuck W/ Muscle Repair & Abdominal/flanks Lipo

I got a tummy tuck because after a rapid weight gain than loss, I had a lot of stretch marks, excess skin, and sever muscle tearage and at 23 I was not happy with that.

What could this bulge be, what are the possibilities? Should I be worried? Should I call the office tomorrow or wait it out until the day after to see if it goes away? Please help!!! -- Updated on Jan 13, 2010: I am 8 days post a full tummy tuck with abdominal muscle repair and minor liposuction on the abdominal and liposuction of the bilateral flanks. I am 23, 5'1, and about 115/120 pounds. I got this procedure because I gained and lost a lot of weight within 2 years and had extra skin and torn abdominal muscles.My recovery has gone quite smoothly this far, however today I noticed that on my left side below my belly button it is more bulged than the right side. To me, it feels a little "mushier" than the other side and is a little painful when I touch it (only the bulged side), but that could be in my head now that I know it's there.My surgery was 12/28/0) and my post-op was on thursday after 12/31/09 and my drain was taken out at that time. My second post-op was last thursday 1/7/10. The doctor said that the bulge was a seroma and that it will go away by itself and not to worry, etc. However, I wasn't feeling good the past few days and I didn't actually vomit, but I was gagging and that left side hurt SOOO much and there was barely any pain on the right. First, is it POSSIBLE that it is a torn suture on my abdominal muscle? AND IF it was a torn/ stretched/ ripped internal suture from the abdominal muscle HOW WOULD I KNOW? AND is thre any way for the doctor to know without going back in or sending me for scans, etc.? PLEASE help I am FREAKING out. PLEASE HELP!!!!!!!!!
