Occasional Itching
Psoriasis: It makes your body overproduce skin cells, which pile up in itchy, inflamed patches on the skin’s surface. Pregnancy: More than one in 10 pregnant women say itching is a problem. Itchy skin is an uncomfortable, irritating sensation that makes you want to scratch. Also known as pruritus (proo-RIE-tus), itchy skin is often caused by dry skin. It's common in older adults, as skin tends to become drier with age. Depending on the cause of your itchiness, your skin may appear normal, red, rough or bumpy. Itchy, itching, tingly, tingling, crawly, crawling, pins and needles, prickly, and any other odd or unusual feelings and sensations anywhere under the skin and/or inside or deep inside the body can also be caused by other medical conditions.
Itching is an unpleasant sensation that compels a person to scratch the affected area. The medical name for itching is pruritus.
Itching can affect any area of the body. It can either be:
- generalised – where itching occurs over the whole body
- localised – where itching only occurs in a particular area
Sometimes, there may be a rash or spot where the itching occurs.
Mild, short-lived itching is common, but the problem can occasionally be severe and very frustrating to live with.
Common causes of itching
Itching can be caused by a number of different conditions, including:
- skin conditions – such as eczema
- allergies or skin reactions
- parasitic infestations – such as scabies
- fungal infections – such as athlete’s foot or vaginal thrush
- hormonal changes during pregnancy or the menopause
- systemic conditions (one that affects the whole body) – such as liver or kidney problems, or an overactive thyroid gland

- using unperfumed personal hygiene products
- avoiding clothes that irritate your skin, such as wool or man-made fabrics

When to see your GP
Many cases of itching will get better over a short period of time. However, you should visit your GP if your itch is:
- severe
- lasts for a long time
- keeps coming back
- associated with other symptoms – such as redness and swelling or jaundice (yellowing of the skin and whites of the eyes)
You should also visit your GP if your entire body itches and there is no obvious cause. It could be a symptom of a more serious condition.
Occasional Itching
Your GP will ask you about your symptoms – for example, if you have noticed whether anything makes your itch worse, or if your itch comes and goes. They will also examine your skin to look for any visible symptoms.
Occasional Vaginal Itching
In some cases, they may take a skin scraping or a swab so it can be tested to help identify the cause of your itching. A blood test may also be carried out to look for underlying problems, such as thyroid or kidney disease.
Occasional Penile Itching
Depending on what is found to be causing your itch, you may be referred to a hospital specialist for a further assessment and specific treatment.
