I had a clue what the diagnosis might be when I was asked if I could “squeeze in Sally Smith for leg numbness and a groin rash”, although I didn’t know the extent of the numbness or the specifics of the rash.

So we double-booked her and I listened to her story. The numbness was only in the front of her left thigh and started somewhere around the groin. Her strength was normal and the sensation below the knee was perfectly normal.
