Orthopedic problems and handbags

I fell on the street nearly three months ago and hurt my knee and my elbow. The pain from my elbow is radiating to my fingers. I've noticed that since the injury, carrying my COS bag, even though it has a thicker strap, causes me a pain in my shoulder, which it hadn't caused before.

The interesting thing is that my Longchamp, with a much thinner handles, doesn't cause any pain at all. My MJ tote bag doesn't as well, but the strap that thing has is nearly orthopedic with how comfortable it is. Adding pictures of the bags I'm talking about.

Has anyone dealt with a similar issue? Maybe it's not related to the thickness of the straps or handles and im just doing something wrong? I try not to overstuff my bags.

I'm using my COS bag a lot because it's the biggest one I have, but I'm considering retiring it for a while .
