The pain began as a dull off-and-on ache between my shoulder blades. But then, seemingly overnight, it progressed into a persistent, sharp and stinging sensation that moved beyond my neck and down into my arm. The unrelenting pain woke me up—and kept me up—at night.
And the more I felt the pain, the more I tensed up and the tighter my muscles became, which only added to my discomfort.
In no time, I became stressed and sedentary, short-tempered and depressed.
