My brother suffers with very tense muscles around the shoulders and neck areas as well quite often, at the bottom of his back. About 2-2.5years ago he was diagnosed with a condition called Spinal Stonosus. A condition which causes the spine to shrink in circumference and the back to get stiffer. Four years ago he suffered an attack of deep vein thrombosis which he has largely recovered from.
