Itchy skin is an irritating sensation that makes you want to scratch and it can be uncomfortable. It is also known by the medical terminology "pruritus". Itchy skin can happen to anyone of any age, race, or gender as there are many different reasons to have itchy skin. It is more of a symptom than a medical condition and can be a symptom of many medical disorders ranging from mild to serious. It is an inflammatory reaction of your skin and can cover just a small area or your whole body. Depending on what is causing your itchy skin determines how frequent you have it, how long you are going to have it, and how severe it will be. Being a symptom it can occur by itself or with other symptoms.


When you have itchy skin it can occur in a small area like on your leg, arm, or neck, or it can occur on large areas like your back or stomach. It can happen without any other changes that are noticeable on your skin. It can also be associated with any of the following:

  • Redness in the area that itches
  • Having blisters, bumps, or spots
  • Skin that is cracked and dry
  • Your skin may have a scaly or leathery texture to it.

It is advisable to see your physician or dermatologist if you have itchy skin that:

There can many reasons that a person has itchy skin. Some of the reasons may include:

  • Autoimmune disease which are caused by the immune system acting abnormally. It will trigger antibodies against the body’s own tissues and can lead to severe itchy skin in some people. Some of those autoimmune diseases that can lead to itchy skin include vasculitis, systemic sclerosis, and rheumatoid arthritis.
  • Having a disorder of your central nervous system can have itchy skin as a symptom but not all the time. If you are suffering from a disorder such as a tumor or brain abscess you can have the itchy skin symptom. You could also have itchy skin as a symptom from epidural anesthesia that results from having an injection of anesthetic into your epidural space of your spinal cord.
  • Having dermatitis which is a skin inflammation that is non-infectious and is characterized by a rash that is itchy and red. It can be caused by ingesting, touching, or inhaling certain things. Some of the more prominent types of dermatitis that can cause itchy skin include atopic dermatitis, photodermatitis, contact dermatitis, and stasis dermatitis.
  • Having dry skin, also known as xerosis is a very common cause of itchy skin. It can be caused by temperatures that are low or high with humidity levels that are low.
  • Hormonal disorders or imbalances in hormones can also lead to having itchy skin. In women it could happened during the later months of their pregnancy or during menopause. It could also be a complication of diabetes.
  • Being bit by an insect can cause itchy skin that last for a few hours or up to several days.
  • Irritants such as laundry detergent or soap can lead to itchy skin.
  • Having an allergic reaction to certain medications
  • Have a nutrient deficiency such as a deficiency in vitamin A and iron. If you lack vitamin C you can disrupt the formation of collagen and cause the itchy skin.
  • Excessive sweating can also cause you to have itchy skin.


Before any treatment can be started the physician must first find out what is causing your itchy skin. Once the cause has been identified your physician may:

  • Have you use corticosteroid creams that are applied to the area to help control the itch. They can be purchased over-the-counter or the physician can give you a prescription for a stronger cream. After applying the cream you should cover it with a cotton material that is damp.
  • Have you use oral antihistamines.
  • Treat the disease that is causing your itchy skin.
  • Using light therapy to help get the itching under control.
