Painful blisters – is it sunburn or shingles?

It sounds so innocent, but people who’ve suffered from shingles say it can be incredibly painful. And with almost 90% of people at risk, be prepared if it ever comes your way! Shingles can easily be mistaken for sunburn. But it’s a lot more painful than that. Here’s how you know if the rash could be shingles:

How it is caused

The condition is caused by the varicella-zoster virus, and it usually attacks people with weak immune systems from injury, stress, illness, certain medication or other reasons. Shingles usually appear in a band, a strip, or a small area on one side of the face or body.

Symptoms

The first symptoms usually include tiredness and headache, followed by itching or tingling in one area of the skin. A few days later, you might notice a chickenpox-like rash, starting with red patches that form clusters of small blisters. In most cases, shingles can last for up to five weeks, and may leave scarring.

Am I at risk

Unfortunately, there’s no way of knowing who will develop shingles and what could trigger the virus. Some research shows that the risk of shingles increases as you get older. The good news is that it’s not contagious so you can’t catch it or spread it through touch, but you could spread the virus to a child or pregnant woman and cause chickenpox.

Stages of shingles

  1. Chickenpox: The virus that causes chickenpox causes shingles. Even after the chickenpox infection is over, the virus stays in your nervous system.
  2. Reactivation shingles: When your body’s defense is down the virus can reactivate and trigger the development of shingles.
  3. Rash: Patches of red bump blisters on your skin.
  4. Crusting: After about a week or 10 days the blisters will start to crust and scabs will fall off.
  5. Postherpetic neuralgia: This is the complication of shingles. It affects nerve fibres and skin. The painful burn lasts long after the rash and blisters caused by shingles.

Shingles pain difficult to treat

According to Dr Milton Raff, a specialist in treating chronic pain at the Christian Barnard Memorial Hospital Pain Clinic in Cape Town, shingles-related pain is difficult to treat and the pain is a result of affected nerves that function abnormally.

“Regular pain medications are not effective. We only have a few specialised medications we can try. If these prove to be ineffective, then the pain can be incapacitating. In a small proportion of patients, the pain never goes away. Not only does the patient suffer severe pain, they can often not perform routine everyday tasks”, says Dr Raff.

Commonly used medicines to treat shingles include antivirals and medicines for neuropathic pain. These cost about R800 a month.

Shingles can be prevented

There is good news, though. Studies show that a vaccine can prevent the development of shingles in up to seven out of 10 people who would have got it had they not been vaccinated. The vaccine also significantly reduces the development or severity of the pain.

The vaccine stimulates the body’s immune response to the virus, without actually causing disease.

In South Africa, children can be vaccinated against chickenpox as part of their routine vaccination schedule. A new vaccine is now available, and it’s just as important for adults over 50 to be vaccinated against shingles. “I would recommend that everyone over the age of 50 should speak to their doctor about getting vaccinated,” says Dr Raff.

3 Vital secrets about flu

Winter is here! Warm clothes, an excuse to wear that scarf, hot chocolate and nights in front of the fire sound really great, and they are! However, it’s also the season when viruses declare war on your immune system. This year we bring you 3 key secrets to preventing and beating the nasty influenza virus.

1. Rest really is the best medicine

Do you think rest is for the weak? Guess again! Bedrest is one of the best weapons against the flu. The only way to beat the flu is to let your immune system do all the work. However, if you’re not resting, your body needs to fight the infection AND do whatever it is you’re doing. So it’s best to rest and speed up your recovery.

2. Try not to spread it around

Did you know that you can still pass on the flu virus even after the symptoms are gone? Yes, you’re still technically infectious for 5 – 7 days, even though you feel much better. What should you do for these few days? If your doctor has already booked you off, stay in bed so your body can fight the virus a little more. If you’re not booked off, ask if you can work from home or take another sick day. If you can’t, then don’t feel too bad if someone else gets sick, you did try your best.

3. Strengthen your immune system

If you want to prevent Flu, you need to make sure your immune system is strong. Even if you catch a cold, supporting your immunity can help that it doesn’t last too long.

Take about 1000mg of Vit C daily; make sure you get at least 6 – 7 hours of sleep a night, and try to stay fit throughout the winter. By moving, your blood pumps through your system, your immune-cells are more energised, and your internal ‘security’ is much more alert – catching the virus before it wreaks havoc.

So, are you geared-up and ready to tackle the flu this winter? If it hasn’t caught you yet, make a plan to get your flu-shot: you don’t want to spend your student-holiday in bed, now, do you?!

Can a low-carb diet weaken your immune system?

Carbohydrates have never really had a good reputation. In fact, they seem to be the one food group that people genuinely fear and try to avoid like the plague! But is it a rational fear? Well, that depends which side of the low-carb high-fat (LCHF) diet fence you sit on. But first, let’s take a closer look at what carbs actually are, how they work in your body, and what kind of balance your body needs to keep a strong immune system as we go into winter.

Beat the winter blues! Top 5 ways to boost your immune system

Winter’s just around the corner, and those nasty cold and flu bugs are already making their appearance. So, how can you fight them off? By boosting your immune system! These are my top 5 must-haves to help build immunity against colds and flu this season.

Zinc

Zinc is an essential mineral, and even a slight deficiency can negatively affect your immune function. People most at risk of zinc deficiency include: the elderly, pregnant and breastfeeding women, breastfed babies older than 6 months, vegetarians, people with gastrointestinal diseases such as Crohn’s and Ulcerative Colitis.

Supplementing your diet with zinc can help reduce the duration and severity of the common cold in otherwise healthy people, and it helps with wound healing too. So where can you get it from? Zinc is found in many foods sources, and oysters are the best choice. Other good sources include: red meat, chicken, beans, nuts, eggs and dairy. It’s definitely a good idea to supplement your diet with zinc, especially during autumn and winter, so speak to your pharmacist about a zinc supplement to suit you.

Selenium

Selenium is a trace element that helps strengthen immune system function as well as Thyroid and reproductive health. Dietary sources of selenium include seafood, nuts (specifically Brazil nuts), organ meats such as liver, and dairy. By taking selenium (either alone or in a combination supplement) your immune system will thank you.

Vitamin E

Vitamin E is a powerful anti-oxidant, and can be found in foods such as nuts, seeds and vegetable oils and green leafy vegetables. Vitamin E supplements usually come in combination with others – so add it to your list of must have immune boosters!

Vitamin C

Good old vitamin C is also a potent antioxidant and immune booster – and it’s a perfect daily supplement to help prevent colds and flu. Citrus fruits such as oranges, tomatoes and berries are all great natural sources of vitamin C. And if you’re a smoker, then listen up: smoking (even second hand smoke) puts oxidative stress on your body, and this eats up your vitamin C reserves! Smokers need double the amount of vitamin C than non-smokers, to keep their blood levels normal. Yet another reason to stop! Aim for at least 500mg – 1000mg of vitamin C daily.

Vitamin A

Vitamin A is essential for healthy sight, immune function and reproductive health, and it’s found in food sources such as organ meats, green leafy vegetables and dairy. If you eat a varied diet, it’s fairly easy to make sure you’re getting enough. However, pregnant or breastfeeding women, and young children risk becoming deficient. Very importantly, if a child develops measles and has low vitamin A levels, the disease can become severe, and vitamin A supplements can be life-saving. Speak to your doctor to find out if your family could benefit from this type of supplement.
Remember, taking too much of anything can be detrimental to your health, so when choosing a vitamin or mineral supplement always make sure that it’s suitable for your age.
