Turns out my shoulder pain is resultant of a poorly administered Maxolon injection during the Last Bad Migraine episode. The locum doctor who gave me the shot went too high in the muscle with too long a needle (i.e. using the right needle length for a 24 year old female, but not a 24 year old female with 11% upper arm body fat [my right arm is 14% which makes even less sense]) and went straight through the deltoid and into the bursa. Apparently 1 in 3 recover fine, another 1 in 3 need surgery, and the last third just live in pain forever which isn't very reassuring. My left hand is very weak and crummy and a huge liability at the moment. Typing this is hard because my fingers only hit 1 in every 5 keys (I'm not counting). Writing this took all evening which is kind of sad. I have to wait 2 weeks to get a blood test which will determine whether the muscle is wasting. Anyway I am still alive and here's a photo
