Due to an illness that has left one side of his face paralyzed, he has had to cancel his upcoming concerts.

A Canadian pop star has a condition. The varicella-zoster virus is the cause.
The virus can stay in the body for a long time after a person has recovered from it. There is a collection of nerve cells next to the spine.
The virus doesn't cause any symptoms while it's still active. It becomes active in some people. A weakened immune system or stress can be the cause of this.
All of these things cause the immune system to work differently, which in turn causes the varicella virus to return to action and cause disease.
Shingles is a painful rash and blisters that appear in a single section of the body when the virus is reactivation.
The doctor who first described the disorder in 1907 named it after him.
Anyone who has had chickenpox can potentially be affected by Ramsey Hunt syndrome.
The facial canal allows the brain to get to the face. The left and right sides of a person's face can be supplied by one of the two brain hemispheres.
The narrow tunnel is inside a dense piece of bone, which can cause inflammation and cause the nerve to be pinched. It can be hard to treat because it is deep in the skull.
Some people with Ramsay Hunt syndrome have hearing and balance problems because the facial nerve travels with the vestibulocochlear nerve.

The symptoms of this syndrome vary from case to case, but there is usually a paralysis of the facial nerve which makes it hard to smile or frown. Some people have slurred speech and can't blink due to it.
On the other side of the ear, there is a rash that is similar to the paralysis. There is a sign that this is not Bell's palsy.
There is a risk of damage to the eye's cornea, which is the part of the eye that protects it from harmful rays. This is due to the lack of blinking.
The facial nerve can cause paralysis. There is fluid in the eye.
People with the syndrome may need to use artificial tears to lubricate their eyes. At night, the eye needs to be closed.
Steroids and painkillers are usually used for treatment. It's best to start treatment early in order to make a full recovery.
70 percent of people make a full recovery if they are treated within three days. The chance of a full recovery drops to 50 percent if treatment is not started in this time frame.
We know that he is getting good treatment and will make a full recovery.
