Armpit Itch Symptoms

Odor is not the only issue of the armpit. When you just cannot stop scratching under the arm, you have armpit itch. The condition can be both uncomfortable and awkward to deal with. We combat the armpit's propensity for perspiration with deodorant and antiperspirant and the area is often shaved to eliminate hair [6].

Armpit itch may result from a variety of factors and presents itself with the following symptoms:

The armpits are in a tricky spot. Nestled between the arm, shoulder, and chest, they are more of a location than a body part. The sweat gland for the underarm is located in the armpit causing the production of the majority of our body odor and also perspiration [7]. A large number of nerves are located in the armpit making it sensitive and sometimes ticklish. The combination of its warmth and dampness and the frequent presence of body hair makes them a prime candidate for itching. Under many circumstances, armpit itch symptoms are a product of the environment, but other causes are more significant and warrant different treatments.

Armpit Itch Causes

Sometimes, even the best intentions can lead to unanticipated consequences. The way we treat our armpits can often lead a variety of symptoms, including armpit itch. Other times, however, there is more to the problem than basic bodily functions and reactions. In those cases, it is important to analyze the armpit itch symptoms to best determine the cause.

Environmental causes:

  • Trauma: Irritation to the armpit can lead to itchiness. Improper shaving or ill-fitting bras can cause such irritation.
  • Hot/Cold: The skin reacts to prolonged exposure to either hot or cold dry air. Armpit itch symptoms can be the manifestation of this reaction,
  • Allergies: Certain substances can cause a skin reaction that results in armpit itch. Laundry detergents, deodorants, or clothing materials are all known to cause itchiness [1].
  • Parasitic: Parasites are tiny organisms that live and feed on the body. Scabies [2] and lice are common parasites known the effect the armpit and cause itchiness.

Inflammatory causes:

  • Infection: While bacteria are normally found on the body, sometimes harmful bacteria can penetrate the skin and cause infection, inflammation, and itchiness. Armpit itch can result from a variety of bacteria including yeast, MRSA [3], and other fungi.
  • Autoimmune: Disorders resulting from the body attacking itself are considered autoimmune. Psoriasis is an example of an autoimmune disorder that causes armpit itch symptoms [4].

Systemic disease causes:

  • Metabolic: The body is accustomed to operating in a specific way. When daily processes are disrupted by conditions like axillary lymphadenopathy [5], armpit itch can occur.

Armpit Itch Treatments, Relief and Prevention

Usually, being only itchy does not raise any alarms, but that does not mean that it should not be treated. Given the wide range of potential causes of armpit itch, taking the condition seriously will help dictate the best course of action to relieve the symptoms. Switching deodorants may be all that is required, or the diagnosis and advice of a medical professional could be necessary.

Contact your doctor if the following accompany armpit itch:

With such a wide range of armpit itch symptoms and causes, self-diagnosis may be a challenge and providing adequate treatment could be equally as challenging. That being said, the most common causes of armpit itch symptoms are treatable at home. It is time to call your doctor though when basic treatments do not work or do not seem appropriate.

At-home treatments:

  • Warm Water Compression: Applying a compress soaked with warm water can help speed recovery from boils.
  • Moisturizer: Repeated applications of lotion to the affect areas can help limit armpit itch symptoms caused by dryness.
  • Hygiene: Ironically, bathing less can sometimes be the cure. Frequent bathing can dry the skin or repeatedly introduce irritants to the skin. Avoiding certain deodorants or soaps may also help. Changing clothes frequently and washing them at high temperatures will help eliminate parasites [8].
  • Over-the-Counter Medications: Creams or ointments designed to treat fungal infections are available for use [9].

Professional treatments:

  • Prescription Medications: Oral antifungal medications or antibiotics may be necessary for more significant causes of armpit itch such as MRSA. Medication also exists to kill parasites.

At a minimum, armpit itch is an annoying nuisance. At worst, it is a sign of a far more serious condition requiring advanced medical treatment. Treating your body right and continued good hygiene practices are often positive steps towards relieving the itch, but, it is always important to remember that advanced cases of armpit itch symptoms require input from a medical professional [10].
