Thanks for all the feedback.

Best I can do with respect to seating on the CRJ is a "seat request card" - even after advising I need an aisle, handicapped accessible seat. Requested wheel chair, said I can move somewhat on crutches if necessary, but I cannot do any stairs, including aircraft stairs as I'm certain there will not be a gate upon arrival with the CRJ - just the built-in stairs with a follow the marked path to the terminal and stairs going up to the departure level.

As it is, I'm having some trouble getting around house on the crutches as I get used to them -- and, yes, it is a good workout for the arms and hands -- but will see how things are in the morning, see if pain is up or down, if I can get the leg to hold some weight, and then decide to go or postpone.

No staples or metal with the dressing covering the wound - but it's painful enough that I will not let a TSO pat down over the dressing under any circumstances.

Looking at their SOP, it seems they're only supposed to pat down if there is an alarm -- but I wouldn't put it past them to do a full body pat down. I'm tempted to wear shorts so that the dressing & injury area is visible. This way they can visually observe, but I will not let them touch it under any circumstances. I can't easily remove shoes either, especially on the leg that was injured.

Will see what happens in the AM, but I will hold my ground. I'll happily get up on crutches for screening, but I won't stand on both feet or do anything that will subject me to pain, cause harm, or pro-long the injury.
