Oh so itchy!
As if ants are crawling on you
Probable cause: Menopause. Changes in hormone levels can produce an itchy skin condition called formication.
Sufferers have the phantom sensation of insects crawling on their skin, though it’s not clear why. One theory is that fluctuating hormone levels may affect nerve endings in the skin.
Treatment: Increasing your intake of omega-3 fatty acids (found in oily fish) can help improve the skin condition, and if the skin is less dry it may be less prone to itching, says Dr. Tabi Leslie, a dermatologist at St Thomas’ and Barnet hospitals in London.
Drinking plenty of water to keep the skin hydrated may help reduce irritation, as can avoiding smoking, excess sun exposure, stress and lack of sleep.
Hormone replacement therapy may also help.
Fiery itch and red, weepy skin
Probable cause: Allergy. Often referred to as allergic contact dermatitis, this occurs when the skin reacts to something touching it. Common triggers include nickel jewellery, rubber gloves or a buckle from a belt. It can also be caused by irritants such as chemicals in soaps or perfumes.Allergens produce an immune response in the skin, which triggers the fiery itch.
In severe cases the skin can become scaly with painful cracks developing on the fingers, says Dr. Andrew Wright, a dermatologist at Bradford Hospitals.
People with a tendency to asthma, eczema and hay fever develop contact dermatitis more easily than others, possibly due to a compromised immune system, and this tendency can run in families.
Treatment: The first step is to identify the cause, says Dr. Wright, so monitor what you use when you get an outbreak. Patch testing may help.
Prickly, intense itchiness
Other symptoms: Sudden rash or mild red patches.Probable cause: Eczema. One in five people will be affected by eczema (also known as dermatitis) at some time in their lives.The condition is caused by an over-reaction of the immune system. Atopic eczema tends to be hereditary and many sufferers will also have hay fever and asthma.
Prime sites are behind the knees, elbows, side of neck or around the eyes and ears as these areas become hot and clammy.
Pompholyx eczema affects one in 20 people, and produces a burning itching along with tiny blisters on the sides of the fingers, palms and feet.
The cause isn’t known, but it can be triggered by perfume, athlete’s foot or stress.Treatment: Keep the skin well moisturised because dry skin is more easily irritated, says Dr. Leslie. Use creams free from chemicals such as parabens. Hydrocortisone can also be soothing.
Itchy red-brown rash
Probable cause: Medication. Some drugs, such as penicillin and other antibiotics, can cause itchy skin, says Dr. Wright.
This is because the drugs are treated as a foreign chemical in the body and produce an allergic reaction within hours.
Treatment: Speak to your doctor about changing your medication.
‘Desensitisation’ can be used for penicillin allergy if the drug has to be taken regularly.
Burning rash from being in the sun
Other symptoms: Small red spots or blisters.Probable cause: Sun allergy. As little as 15 minutes in the sun can trigger polymorphic light eruption, an immune reaction that causes a burning itchy rash on the chest and arms.
This occurs about a day after the first exposure and produces small red spots or blisters. It affects around one in ten people, and is more common in women than men.
Treatment: Calamine lotion, or corticosteroid cream and antihistamine tablets, can help. To prevent it, try exposing yourself to sunlight gradually.
General itching and hot, painful skin
Dry skin often feels itchy as it is more easily irritatedProbable cause: Urticaria. Also known as hives, this condition occurs when too much histamine — a chemical produced in response to an allergen — is released by the cells in your skin.
There are two types: acute and chronic. Acute urticaria occurs after a cold or flu, an insect sting or contact with chemicals in food such as tomatoes, tuna, strawberries and bananas.
Chronic urticaria lasts more than six weeks, and occurs when antibodies from your immune system attack the body, causing the release of histamine. Alcohol, stress and high blood pressure tablets can make the condition worse.Treatment: Over-the-counter antihistamines can help. But avoid non-steroidal anti-inflammatory drugs, such as aspirin and ibuprofen, as these can also produce an allergic reaction that would exacerbate the condition.
Mild, constant itch and red patches
Other symptoms: Silvery white scales. Probable cause: Psoriasis. Around one in 50 people have this condition, where the skin grows about seven times more quickly and thickly than usual.
Psoriasis often affects the elbows, knees, lower back and scalp and usually strikes between the ages of 15 and 30, or after 40.
It is thought to be linked to an abnormal immune reaction, but it can be triggered by stress and hormonal changes.
Treatment: Sun exposure can help as it boosts levels of vitamin D, which is thought to dampen skin growth.
Vitamin D is also available as an ointment.
Bathing in warm water with a bath oil or tar solution can soften psoriasis and lift the scale, says Dr. Sandeep Cliff, a dermatologist at East Surrey Hospital. He also advises cod liver oil as the omega-3 fats help reduce inflammation.
