I may not be describing it well, but it's not really about not being jostled - the nerve is still pretty spicy right now but by the time I'm back to working alone it'll just be about minimizing pressure on my elbow. Longer term I should be fine to wear a padded cuff on my arm, but for awhile I'm stuck padding surfaces.
I'd like to find or make something I can slide over or lash to an airline armrest - I imagine it to be reasonable to hope most seatmates would be ok "sharing" a padded sleeve, if I couldn't get a right side window seat. I'd like to make sure whatever I get matches the width of Southwest's armrests pretty well, was hoping someone might have a decent guess.
