Itchy Bumps on Legs

Itchy Bumps on Legs

Itchy Bumps can appear anywhere on the legs, whether it is on the feet or on the thigh. People who get this type of bumps often have the feeling to scratch it as it is so itchy. They are so frustrating but there is no need to worry about these bumps. These bumps are usually small and itchy, and appear and disappear more often. It is usually not advisable to scratch or burst open the bump as it will open the skin and cause unnecessary infection. Let us discuss some of the common causes for the appearance of these Itchy Bumps.

Itchy bumps are caused by the fluid inn between tissue cells. This is done by our own body in order to isolate areas that might have come in contact with an allergic / harmful substance.

Causes of Itchy Bumps on Legs

The most common causes of itchy bumps may include an allergic reaction to new products, insect bites or poison ivy. The most common causes are:

  • Insect Bites: Insects are found everywhere in earth. These insects’ first contact with the human is through the feet and legs. When insects such as mosquitos and ants nibble our feet, they cause a tiny bump to be formed on the area. Sometimes, these tiny itchy bumps spread all over the area depending on the type of insect that bit us.
  • Allergy: Allergies are caused in skin due to allergens. If a new lotion has an ingredient that is allergic to a particular type of skin, then applying it on the legs and feet would cause itchiness and/or bumps. It is always better to check new products before trying them on the skin.
  • Heat Rash: If your skin is sensitive to the excess heat of the sun, then there is a high chance of getting itchy, red bumps in the part of the skin that is exposed to the sun. Usually, in summer, our feet and legs are the ones affected due to the type of clothing we wear.
  • Shaving: Shaving of unwanted hair causes itchy bumps for almost everyone. This is due to the fact that the blades cut the area surrounding the hair follicles leading to inflammation, infection and itching. Itchy bumps can also appear due to the shaving creams and lotions applied on that area.
  • Hives: Though hives usually appear on the face, they can also appear anywhere in the body. Itchy bumps on legs and feet can thus also be due to hives.
  • Skin Infections: There are many types of skin infections that cause bumps on feet and legs. But a condition called folliculitis is caused by the infection of hair follicles. These infections usually occur after a visit to the hot tub, a skin cut or after a waxing session in the salon. This folliculitis will lead to abscess if left untreated.
  • Anxiety: Some people with anxiety develop itchy bumps on the skin.

There are several other causes like medication side effects due to drug interaction, autoimmune disorders and skin diseases. Taking the help of a medical practitioner is important in treating this symptom.


The treatment for itchy bumps on the legs is done depending upon the cause of the bump. The most common treatment is to treat it with antihistamine drugs. Antihistamine drugs cut down the allergic reaction and reduce the itchiness. Topical creams also help in reducing the itchiness.

  • In case of allergic reactions, the allergens are identified and discontinued.
  • If the cause of the itchy bumps is virus infection, the doctor will have to determine the course of treatment. In case of infections like chicken pox, it has to reduce on its own. But some viral infections have medications available to treat it.
  • For insect bites, it has to reduce on its own. But the cause of the itchy bump can be examined and determined in order to rectify it. For example, if the itchy bumps appear during the night, the cause might be bed bugs and they can be eliminated by calling an exterminator.
  • For heat rashes and rashes due to shaving, soothing lotions and anti-itch creams are available over the counter. These kinds of bumps usually go away on their own.
  • Skin conditions like eczema and psoriasis need to be controlled with the help of a skin specialist. Sometimes, psoriasis might need immunosuppressant drug to suppress the crusty lesions.


Itchy bumps on the legs are not problems to worry about. But if not treated on time, they might turn chronic. It is always better to know the cause of such problems rather than treating the symptoms. Consulting a doctor and getting it treated reduces the possibility of the bumps becoming affected by infections. The thumb rule is to watch for any signs of skin infection, increase in the itchiness of the bumps, and reaching out to the doctor in case of pain or fever.
