You can still have post operative bruising up to 12 weeks after the event. Believe me it takes time for things to calm down. Irritating I know but at least you are feeling fine otherwise which is good. Starvation however is not - don't go there.
Scoutshadow is right, it does take time. I had surgery in July and my clothes are totally different now and I weigh less...enough to go down a size. Hang in there sweetie and give it some more time.
Shopaholic was yours a dermoid by any chance
YES MINE WAS A DERMOID SIZE 21.5 X 21 X 10
I lost a bunch of weight right away after my surgery (they removed an over 13cm tumor-mostly dermoid, but unfortunately some cancerous), but I really started losing when I started working out at the gym. If you have been cleared to exercise, it would be a good idea. I think that's really what helped me get my figure back. I think my hips expanded too, but I blamed that on pregnancy since I had my son just 3 months earlier and was working on losing weight when the alien was discovered. Cheer up! It will happen before you know it!
