The following is excerpted and adapted from Ending Back Pain.
The odd sensation started in her lower back, a little to the right. An avid runner, Kathryn chalked it up to her long jaunt that morning down to the beach and back. She popped some ibuprofen to try to settle the dull sensation. The feeling resembled one of a pinched or agitated nerve, and she assumed this could be another sciatic episode. Or perhaps she had strained a muscle. Whatever it was, she didn’t think twice about her growing discomfort and lower back’s tenderness. If she worried about anything, it was that this escalating soreness would disrupt her run the next morning, and she’d have to take a few days off. By bedtime, she sensed that something wasn’t right. She took another round of ibuprofen and decided that a good long sleep—off her feet—would be the cure.
