Awakened chicken pox virus can cause excruciating pain

A vaccination can prevent a lot of pain down the road.

It starts like a little tingling, or perhaps it’s an itchy or burning feeling. Then you notice red spots somewhere on one side of your body. Within a few days, they start to hurt, hurt like crazy and then the spots turn clear and watery. You have shingles.

“The hallmark is its one-sided rash. It can be very painful. There are blisters. The important thing is the nerve pain that can last for weeks and weeks. In some people, it can last for months and in some people it can be quite debilitating,” says Dr. Meena Dawar, Richmond’s medical health officer with Vancouver Coastal Health Authority.

Shingles can happen to anyone at any age but often they occur past middle age. That wasn’t the case when Anne, who asked her full name not be used, was in her late 30s.

“The first symptoms I noticed were red spots that were only on one side of my torso. They were a little bit itchy,” she says.

Anne worked in a hospital. She saw her doctor who diagnosed shingles.

“When I was diagnosed it was a surprise to me because I had always thought of shingles as a disease of the elderly. I had heard of friends of my grandmother who had terribly painful neuropathy afterwards and infections that affected them,” she says.

When a person has the chicken pox, often as a child, the itchy rash goes away but the the chicken pox hides out in nerves, sleeping until some unknown thing awakens the virus where it infects the nerves, torturing the pain sensors, causing red spots that turn into the tell-tale blisters.

The spots and blisters, Dawar says, are usually on one side of the body only and “in a band-like pattern. That’s important because nerves usually provide coverage in a band-like pattern. That’s classic.”

The virus can also affect the clear cornea on your eye or anywhere else on the body.

Anne was put onto an antiviral medication to stop the virus in its tracks and speed the healing of the skin on her shoulder.

What should you do if you suspect shingles?

“You should absolutely go see your family doctor right away,” says Dawar “Shingles is treatable if treatment is sought early enough. There is antiviral treatment which can be prescribed by your family physician,” Dawar says.

Treatment helps more than just the patient. It makes them less infectious to others.

“The blisters have chicken pox virus in them. Severely immune-compromised individuals have to keep away from all potential infections including shingles,” Dawar says.

For Anne, working around people on chemotherapy—that temporarily robs them of an immune system—meant she had to stay home from work until her blisters healed to keep the patients safe.

“The most important thing to know is it’s preventable. Up to 20 percent of people will get shingles in their lifetime,” says Dawar, “Adults over 50 are recommended to get the shingles vaccine.”

The latest shingles vaccine is more than 95 per cent effective. It means two shots a few months apart. While you do not need a prescription for the shots, you do need to pay for them.

“Shop around,” says Dawar as some pharmacies have different pricing policies. Some private health plans do cover the cost of the shingles vaccine.

The older, single dose vaccine is only 50 to 65 percent effective according to Dawar. She recommends that those who have only had the earlier kind of shingles vaccine go get the newer, more effective shots.

And, if you are in for your flu vaccination, you can safely have it at the same time as a shingles shot, according to pharmacist Jenny Lin at Pharmasave in Richlea Square.

“CDC general recommendations advise that…administration of (shingles vaccine) with (the flu shot) has been studied, and there was no evidence for interference in the

immune response to either vaccine or safety concerns.”

Anne’s been meaning to get her shingles vaccine for some time now. The importance was driven home to her: “When (my husband) was diagnosed with leukemia I wished that I had had it. The risk of potentially having an outbreak and giving it to him when he was immune-compromised was frightening. At one point I had a rash on my torso when he was sick. It turned out to be a reaction to laundry soap. The doctor thought it was probably not shingles because it was on both sides but I went back on antivirals, to be safe.”

FLU SHOT

It’s positively chilly outside, and that means one thing is coming.

The flu.

“We are at the start of the flu season. The campaign has begun, and there’s vaccine available for children and adults. It’s recommended for everybody and provided free for everybody so, go see your family doctor, pharmacist or public health to get immunized.”

Dawar says this year we are seeing H1N1, otherwise called swine flu, as well as the H3N2 strain that killed so many last year and the B strain influenzas, one of which has already killed a previously healthy child in the US, according to the Centers for Disease Control in Atlanta.

Speaking of the H3N2 strain, all the hospitalizations and death it caused, Dawar says, “Last year was fairly heavy.” CDC Atlanta says this year’s flu vaccine better matches the strain of influenza circulating so should be more effective.

With the flu shot, like the shingles vaccine, as Anne says, “It’s not just yourself you are protecting, it’s your family.”
