I've never had that type of pain before, and rarely have any pain. It's totally unusual. The pain presented at about 9:30 a.m. about 8 days after biking accident. Until about 8:30pm on the same day it presented — so for about 12 hours– the pain was somewhat acute: it was unavoidable, but sitting up very straight, and stretching the arm back helped. Breathing very deep as I do fairly regularly with weekly yoga class and every day wake up increased the pain.
It has since subsided a bit, but is still there, in that same location. A deep breath does increase it but not to the level it wasthe first 12 hours. I am scheduled to see my doctor in a month or so, and am hoping this will wait til then – as it's difficult to get in.
