I am beginning to wonder if I DID hurt myself, though I may simply need a stronger anti-inflammatory... The muscular soreness is departing but there is a place in my neck-bone that is just staying tight and while my right arm generally does get all numb and tingly when I walk with it hanging down, it is worse than normal. Of course, that doesn't mean all of the inflammation is gone now that it is harder to find places sore to the touch... I will give it a few more days.
