Indent on left side 3 weeks post gallbladder removal

Hello!

I had my gallbladder removed 3 weeks ago. On Sunday morning I noticed while sitting that the fat was indented near my belly button. It almost looks like a line where my pants sit, but not on my right side just my left. It doesn’t hurt, although i have been poking at it so its a touch tender.

when I stand it sort of feels like a lump on top of it, however both sides look the same size, its just that the left has an indent in it. When i pull up my fat there is no indent or lump.
