I had full abdominoplasty 12 weeks ago. My weight has always been 108-112lbs (have had 3 children). But I feel I still have abd swelling, if I dont hold my abd muscles tight and let them relax, my stomach sticks out (from pubic bone to ribcage). Also my abd muscles get very sore and tight with any activity. Is this normal this far post-op, or was my surgery unsuccessful? please help...I am freaking out.
