itchy legs can be caused by so many things. Itchiness is the skin’s way
of letting us know that some kind of irritant is present, but irritants
can range from minor hygiene issues to fungal or bacterial infections.
When trying to identify the cause of skin irritation it is important to
distinguish between itching, pain, and tingling. Itching can have a
number of causes. Pain may be due to an injury, and tingling may be a
neurological condition.
Below are some of the major causes of itchy legs. If your itchiness is
persistent, consult a physician.
When Itchiness Is a Concern
If your legs itch, it is more than likely due to dryness or some other
mild irritant. Consult a doctor, however, if you experience any of the
following:
Your leg has been itchy for two weeks or more.
The skin is red or inflamed even when you haven't been scratching.
You have other symptoms, such as fever or fatigue.
Otherwise, read on for common causes of itchiness in the legs.
1. Dry Skin
Dry skin is often itchy. Generally, dry skin can be controlled through
environmental factors. It is usually temporary and appears in response
to a dry, hot environment. Severely dry skin is divided into a series of
inherited disorders called ichthyosis.
Causes
The Skin becomes excessively dry when its loses it natural oils.
Too-frequent showering and excessive use of soap can bring this
condition on. Other causes are dehydration, swimming, dry weather, cold
weather and heating systems, excessive sun exposure, and laundry soaps
containing perfumes or dyes. There are inherited conditions, including
hypothyroidism and Sjögren’s syndrome, which can cause very dry skin. As
we age, our skin becomes dryer, so itchiness is a common problem for
older people.
Treatment and prevention
Creams containing lactic acid and urea as well as ointments containing
petroleum jelly, applied immediately after bathing, will help the skin
retain moisture
Limiting baths and showers, as well as use of soap, can prevent dryness
A humidifier to add moisture to a dry room
Detergents without perfumes or dyes
Wearing gentle fabrics, including silk and cotton
Hydrate. Drinking enough fluid (excreting at least 200 ml of clear urine
in the morning can be considered as a sign of good hydration).
Avoid direct wind and sun exposure.
2. Chicken Skin (Goose Bumps)
These are not the same goose bumps that people experience when they are
cold. With this rash, the hair follicles on the thighs, upper arms, or
elsewhere on the skin thicken and develop into itchy bumps. The
condition, medically known as keratosis pilaris, appears as goose bumps
that are skin-, red-, or brown-colored.
Cause
Keratosis pilaris is a build-up of keratin. It is a hereditary condition
but generally disappears by the age of 30.
Treatment and prevention
Keratosis pilaris bumps can be treated so they disappear, but they
almost always reappear. Dryness can worsen the condition.
Creams containing alpha-hydroxy acid, lactic acid, salicylic acid, or
urea may help by both moisturizing the skin and loosening the dead skin
cells to help clear hair follicles.
3. Folliculitis
With folliculitis, the hair follicles on the skin become infected. The
resulting bumps are usually red and itchy. They can also be painful and
may be filled with pus. Generally they appear on the thighs or buttocks,
often in athletes who wear tight sportswear.
Cause
This rash is usually caused by the bacterium Staphylococcus aureus
(staph infection).
Treatment and prevention
With proper hygiene, the bumps should heal on their own within several
days.
If the rash persists, over-the-counter anti-bacterial soaps or ointment
(containing the antibiotic mupirocin) may help.
For widespread infections, oral antibiotics may be the most effective
treatment.
4. Leg Itch in Unfit Runners
When we take a long break from exercise and then go for a run, we may
notice intense itchiness in our legs and abdomen. This condition is
called "runner's itch" and usually affects the thighs and calves the
most.
Cause
Runner’s itch occurs when arteries and capillaries have collapsed due to
inactivity and then re-open when we exercise. The blood vessels opening
up can irritate the nerves adjacent to the capillaries.
Treatment and prevention
The condition should dissipate with training.
5. Acne
Acne is a cluster of pimples with occasional whiteheads or blackheads.
They can appear on the thighs or buttocks and may or may not be itchy.
Cause
Acne may occur due to poor hygiene, psychological stress, or
inappropriate diet.
Treatment and prevention
Increasing exercise and water intake and avoiding fatty foods will help
get rid of acne.
6. Cholinergic Urticaria (Hives)
Cholinergic urticaria or hives is a bumpy rash on the thighs, upper
trunk, or arms and can be triggered by a range of different events or
activities. Generally brought on by sweating, hives can appear after
exercise, bathing, staying in a hot environment, or even emotional
reactions such as excitement, shock, laughter and stress. The rash may
appear a few minutes after the start of a run or shortly after a hot
shower, and can be intensely itchy for 30-120 minutes.
Cause
Hives are thought to be caused by an allergy to one’s own sweat.
Treatment and prevention
Avoid running in hot weather and stop running when itchiness appears. If
possible, do not scratch. Scratching aggravates itching. Oral
antihistamines, taking at least 30 minutes prior to shower or exercise,
may prevent hives.
7. Itchiness After Showering
If your skin loses too much of its natural lubrication during bathing,
it may become itchy and tight.
Causes
Too-frequent hot showers and overuse of soaps that remove the protective
skin fat and oils.
Treatment and prevention
Try showering with lukewarm water instead of hot or warm water. Use soap
sparingly.
8. Jock Itch

itch.

Jock itch, also known as tinea cruris, is a fungal infection of the
skin. Most often this condition affects the inner thighs, genitals, or
buttocks. Jock itch appears as an extensive red or brown itchy rash.
Cause
Moisture and warmth encourage the growth of fungus.
Treatment and prevention
Antifungal ointments or, in persistent cases, oral antifungal
medications
Keeping groin dry (wearing light and comfortable clothing) and washing
with an antifungal soap
9. Poor Hygiene
When dried sweat and dust remain on the skin, they are broken down by
bacteria and yeasts and can irritate the nerve endings in the skin. Heat
and rubbing by trouser fabric and socks can aggravate this sensation.
Treatment and prevention
Bathe regularly. Try to use lukewarm water and mild soaps, not hot
water, to avoid removing the protective fat layer from the skin.
10. Itchy Pants Syndrome
This fancy term describes itchiness from wearing new, unwashed pants or
trousers.
Cause: Irritating substances in unwashed fabric.
Treatment and prevention: Bathe and wash clothing.
11. Eczema
Eczema is a group of conditions that cause skin inflammation and
irritation. Nearly 20 percent of infants are afflicted with eczema but
most outgrow it by their tenth birthday.
Causes
It is unknown what causes eczema, but it is thought to be an overactive
immune response to irritants.
Treatment and prevention
Untreated, an itchy eczema rash may become infected. Lotions and creams,
applied when the skin is moist, can help the skin retain moisture. Cold
compresses also relieve itching. Hydrocortisone (1%) cream, or
prescription creams and ointments containing steroids, may also be
prescribed to reduce inflammation.
12. Stasis Eczema
Stasis (gravitational) eczema appears as rough, reddish, purplish,
swollen, itchy skin on the lower legs. It is most common in cases where
there are circulatory problems, including varicose veins, vein
thrombosis, or other blood vessel-related disorders.
Causes
Inflammation from circulatory disorders allow for fluid build-up. Fluid
leaks out of the veins into other tissues, causing itching and
irritation.
Treatment and prevention
Corticosteroids, including hydrocortisone, can help to treat the rash.
Wearing compression stockings and avoiding standing may help prevent
this condition.
