What causes overstimulation of the vagus nerve?

Here’s how: When someone is extremely stressed, the vagus nerve can get overstimulated as it works to bring down heart rate and blood pressure. This may cause someone’s heartbeat to slow down too much. Blood pressure may now plummet. Under these conditions, too little blood reaches the head — causing someone to faint

In addition, the spinal accessory nerve also goes to the SCM and upper trap muscles, which are also muscles that are commonly tight in these patients

How do you fix cervical instability?

What spinal nerves affect the bladder?

The lower urinary tract is innervated by 3 sets of peripheral nerves: pelvic parasympathetic nerves, which arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra; lumbar sympathetic nerves, which inhibit the bladder body and excite the bladder base and urethra; and pudendal nerves.

How long does it take for bladder nerves to heal?
