M.,
I can definitely relate...as many other members can as well, I believe!
Tension is a likely culprit...coupled with a tendency to focus on aches/pains/body sensations...and attach worries to them!
Check out our Resources and look at the health anxiety links....as well as the 'Stress Relieving Exercises' to learn Progressive Muscle Relaxation for relief.
Wishing you well...body and mind.
