No it is muscular: This is ok and you are doing your own spinal manipulation like cracking your knuckles. You are most likely "cracking" your facet joints (the small joints of the spine-2 at each level) which stretches their joint coverings or capsules which causes a reflex relaxation of the surrounding muscles. There is no harm in you doing this in the neck or back as well as with the fingers.
