I am 3 weeks on my post op and have been doing really pretty good. no pain at all hardly.. now this morning I got up and my stomach was sore and noticed tighness around the lower part. Is this normal? I took out my stitches this weekend and one was opened a bit. I've kept a butterfly bandage on now but still had some draining.. hopefully all is healing well inside.. has anyone had this happen to them in the 3rd week of post op??? I'm concerned..
