Things "getting on your nerves"?
These are what your nerves look like. Fascinating aren't they?
Muscular tension can put pressure on your nerves (just look how fine they are, how easily 'squashable'), irritating them and sending pain-signals to the brain, not only for the zone of entrapment, but also in referred areas too.
A good massage can soothe that compressing muscle and stretch it so that it stays loosened, untrapping pinched nerves, and literally (ahhh the relief!) switching off pain-signals.
Massage Therapy: good for getting things OFF your nerves.
