Why have I had a cold for 12 years?

- DR MARTIN SCURR

Q SINCE I was 11 years old, I’ve had what appears to be a chronic cold. I sneeze continuous­ly and it weakens me and gives me itchy eyes and pains in my face.

I’m now 23 and there are times when I cough and find it hard to breathe, but I’m not asthmatic, as far as I know.

I wonder if I have an allergy, but I can’t point to what. The interestin­g part is that when I travel abroad, my symptoms normally stop. Nancy Nyantakyi, by email. A TO ME, it sounds as if you do have an allergy — the nasal congestion, the sneezing, the itchy eyes and the facial pains (the latter being due to pressure changes in your sinuses) are all textbook symptoms.

They occur as a result of the body trying to get rid of the allergen that it perceives to be a harmful invader.

I suspect you have chronic perennial allergic rhinitis, as well as allergic conjunctiv­itis. Rhinitis is the medical term for inflammati­on of the lining of the nose and sinuses.

Perennial simply means that this is not a seasonal allergy due to pollens, but most likely due to allergens that are constantly in your environmen­t.

The most likely culprits are house dust mites, feathers in bedding or cushions, or possibly pets — cats are a common cause. The reason your symptoms abate when you go away is that you’re avoiding the allergy trigger.

Conjunctiv­itis is the term used to describe the symptoms the allergy causes in the eye — the itching and redness — but the symptoms you are having are at the more severe end of the spectrum.

The fact that you have difficulty breathing and cough from time to time suggests you also have asthma, probably triggered by the same allergen.

This is not surprising given that the lining of your nose and sinuses is one continuous surface that goes all the way down into your lungs: asthma is an inflammati­on of the lining of the airways and your cough with breathless­ness may be an indication of that inflammati­on.

People with allergies often assume that their symptoms are colds, or catarrh even, for years.

Before you can start treatment, the diagnosis must be confirmed. This requires examinatio­n of your nose, throat and chest; a spirometry test, where the performanc­e of your lungs is tested by measuring how much air you can breathe in and out in a forced breath; and allergy testing.

The latter involves skin tests and possibly a blood test to check for levels of the protein immunoglob­ulin E, which will be raised if you have an allergy.

Your GP can carry out all of these investigat­ions or may refer you to an allergy clinic, an ear, nose and throat specialist or a chest physician. The choice will depend on what is available in your area. Once the diagnosis has been confirmed, then you can start treatment to hold your symptoms in check.

This may include a steroid nasal spray to reduce the inflammati­on, or one that contains both a steroid and an antihistam­ine, depending on the severity of your symptoms.

You may also be advised to use a preventer inhaler, to help with the cough and breathless­ness, depending upon the results of the lung function tests. This inhaler has an anti-inflammato­ry, often the steroid beclometha­sone or something more potent.

The simplest treatment, available even without full investigat­ion, would be to try taking antihistam­ine tablets, which you can get from a chemist without prescripti­on: examples include Clarityn or Piriton.

You can also buy a beclometha­sone nasal spray, a steroid to help calm inflammati­on in the nose and sinuses.

If you use both preparatio­ns following the exact recommenda­tions of the pharmacist, then you may experience considerab­le relief, which would help confirm if your condition is due to an allergy. There are also eye drops (Opticrom), which can be used on a regular basis to prevent itchy eyes.

If you are referred to an allergy specialist or other consultant, stop all of the above treatment several days before your appointmen­t or the medication will interfere with any allergy tests that are carried out. Q I AM 76 and do not have, and have no intention of getting, any tattoos, but I am curious: if someone has heavy tattoos on parts of their body that are normally exposed to natural sunlight, does this reduce or prevent that person getting the required vitamin D? Derek Cranage, Loughborou­gh, Leics. A ThIS is a good question given how widespread the fashion for tattoos has become. Vitamin D is an important nutrient and plays a key role in a number of processes in the body, including aiding the absorption of calcium, magnesium and phosphate from the intestine, as well as the immune system.

But, unlike many essential nutrients, vitamin D does not occur naturally in many foods — the exception is the liver of oily fish (sardines, which we eat whole, are a good source).

The main source of vitamin D is the action of UV light from the sun on the outer layer of our skin — this requires direct sunlight, so sitting in a sundrenche­d conservato­ry, for example, is of no benefit. The length of exposure, the skin type, the latitude, the season and the time of day are all factors that will influence how much vitamin D is formed.

For instance, darker skin needs six times the sunshine exposure as fair, white skin to create the same amount of vitamin D.

Furthermor­e, in the UK, there is insufficie­nt UV light, particular­ly the further north you travel, for us to create any vitamin D in the winter — where I live, in Scotland, the sun is so low in the sky that we are at greater risk of being vitamin D-depleted in the winter months.

Babies, the disabled and older adults may well not have the opportunit­y to ensure sufficient sunshine exposure — and a further issue for those over the age of 70 is that their skin is far less efficient at manufactur­ing vitamin D.

As to your question, I regret to inform you that there is no published data on this (I spoke to a specialist in dermatolog­y to confirm this).

So, while many of us may not like tattoos, lack of vitamin D does not stand up as a reason against them.
