Maybe it's a flare-up in response to the showering, brushing teeth, eating - all the associated arm movements. I know for me, by the time I finish showering, washing, drying, (minimally), and styling hair(minimally), putting on just basic foundation and powder and getting dressed for church I am EXHAUSTED. Most days my hair's in a pony tail and I'm bumming 'round in shorts and tees or the like. Washing and drying my hair is one of my least favorite things to do!

Wonder if you could test this by showering the night before, or taking a warm bath in the morning for a few days, see if the pattern changes or stays the same?
