A year or so ago, I was experiencing pains running from the back of my head, on the right side, down through my neck and into the shoulder. I was imagining all kinds of possible ominous reasons for this, and finally went to my doctor. He ran a number of tests that couldn't point to any obvious cause. I started thinking in detail through my daily routine and remembered that I had been lugging my computer bag (using the shoulder strap) quite steadily over the preceding weeks. Once I stopped doing that, the pain went away. Sometimes the explanation for pain is straightforward and not life-threatening, thank goodness.
