Mental stress often has physical manifestations.
Many people "hold stress" in their upper backs, necks, and shoulders. When mental stress creates muscular stress, pain is not far behind.
Muscles that are too tense cause pain. Anxiety and stress causes muscles to be engaged for a prolonged period of time. These tight muscles pull on the skeletal structure and lead to alignment problems.
Treatment of muscular stress often provides immediate relief.
You have enough stress in your life, the last thing you need is back pain adding to your worries.
