?
would it be hard to have an arm in a sling?
I have a few places I will go after surgery where the people don't always think, plus everyone doesn't know me. There is a lot of shaking hands and possibility of being bumped into. I can isolate myself some from the crowd, but someone there suggested I put my arm in a sling, as a caution sign. Something that would get there attention to be careful around me.
