Nerve Damage (Definition)

A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more

Can degeneration of the C5-C6 vertebra cause episodic syncope due to vagus nerve damage or entrapment?

Can degeneration of the C5-C6 vertebra cause episodic syncope due to vagus nerve damage or entrapment?

No but VBI might: VertebroBasilar Insufficiency (VBI) - The vertebral arteries run up the back of the neck thru tunnels (foramen) in the vertebrae (bones of spine). Some neck maneuvers can compress the artery where it passes thru the foramen. While not usually syncope, this can cause vertigo & drop attacks via buckling of the knees usually in older folks with degenerative spinal problems. aka beauty parlor syndrome. ...Read more

What type of doctor can determine if I have had vagus nerve damage from lap band surgery?

What type of doctor can determine if I have had vagus nerve damage from lap band surgery?

Special Blood Test: Unfortunately, there is no 100% diagnostic test to confirm vagal nerve injury. Gastric emptying studies are often ordered but are notoriously unreliable. The best test is measurement of pancreatic polypeptide (pp) after Insulin administration. Normal secretion of pp is mediated by the vagus nerve in response to low blood sugar. If the vagus is injured, the pp level remains low after insulin. ...Read more

I developed anxiety and PVC'S after fundoplication. Vagus nerve damage?I was fine before surgey!!

I developed anxiety and PVC'S after fundoplication. Vagus nerve damage?I was fine before surgey!!

Yes, it is possible: Damage to the vagus nerve is a known risk of fundoplication. How often this occurs has been investigated but has not been determined. Because increased tone of the vagus nerve can suppress PVC's, it is a reasonable possibility that new onset PVC's after fundoplication could result from damage to vagus nerve during the surgery. ...Read more
