4 weeks tomorrow since lap appendectomy. i lifted some heavy grocery bags and carried them upstairs. it slipped my mind. is it okay or should i worry?

Lap Appy: I have performed many a lap Appy. From what you have shared it sounds like if there was something to be worried about it would have definitely shown up. I would say that you are safe, though I would add that you should keep an eye on the area to ensure that there is no hernia tigon, which would demonstrate its prescience with a bulge. Essentially you are fine and I would say be careful.
