I am about 1 week and 4 days post op. I have discovered a good size knot about 3 to 4 inches above the place I was told was my port incision. Just wondering if this is normal or if anyone eles has experienced this before. It is a lil painful and I'm not sure if it is something I should contact my dr. about or it this is, like I asked before, normal? I have my 2 wk. post op appt in 4 days but if it's not a normal I want it checked out asap. thanks to all read this!
