When the cardiovascular center in the medulla oblongata receives this input, it triggers a reflex that maintains homeostasis (Figure 2): When blood pressure rises too high, the baroreceptors fire at a higher rate and trigger parasympathetic stimulation of the heart. As a result, cardiac output falls.

With a pain solver, however, our nerves become unblocked and begin to receive impulses again. This re-awakening of our healing nerves is felt through slight tingling sensations often described as a "pins and needles" effect. This is a normal reaction of the nerves as they work overtime to regain normal function.

The normal response is a 'knee jerk'. This is an example of a reflex, which is an involuntary muscular response elicited by the rubber hammer tapping the associated tendon. When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged.
