  • Vitiligo

Causes & Symptoms

What is the Cause of Eczema Skin Disorders?

Eczema (atopic dermatitis) is a condition that makes your skin red and itchy. Although common in children, it can occur at any age. Eczema is chronic, and will continue to flare up periodically over time. For some, flare-ups may be accompanied by asthma or hay fever.

Currently, there is no known cure for eczema. Your MD Now provider may recommend treatment and self-care measures to help relieve itching and prevent outbreaks.

What is Usually the First Sign of Dermatitis?

Dermatitis is a general term for skin irritation. This common condition has many causes and occurs in many forms. Dermatitis symptoms and treatment tend to be just as diverse.

Consult your MD Now doctor for dermatitis symptoms and treatment. Treatment may include relieving common symptoms, such as itchy, dry skin, or rash over swollen, reddened skin. Additional treatment may be needed for blistering, oozing, crusting, or flaking associated with eczema, dandruff, and contact dermatitis (caused by allergies).


What is the Relation Between Severe Cellulitis and Diabetes?

Foot infections, such as cellulitis, are a common problem among those with diabetes. These infections can be difficult to treat due to impaired circulation. People with diabetes and others with poor circulation should take extra precautions to prevent skin injuries. Check feet daily for signs of infection, moisturize regularly, wear appropriate footwear, and promptly treat skin infections, such as athlete’s foot.

See your MD Now provider immediately if you suspect you may have cellulitis. This common, potentially serious type of bacterial skin infection occurs when a crack or break in your skin allows bacteria to enter. Affected skin appears swollen and red, and will usually feel painful and warm to the touch. Although rare, cellulitis can spread to your lymph nodes and bloodstream, impact the deep layer of skin tissue, and create an extreme emergency.

Visit MD Now Promptly If You Experience:

  • Shaking/Chills
  • Feeling ill
  • Fatigue
  • Sweating
  • Dizziness or lightheadedness
  • Muscle aches
  • Warm skin

These Symptoms Suggest Cellulitis May Be Spreading:

  • Drowsiness
  • Lethargy
  • Blisters
  • Red streaks


Does Psoriasis Go Away Without Treatment?

Psoriasis is a chronic skin condition that commonly causes a rash on elbows, knees, genitals, and toenails. Depending on its severity, psoriasis can be treated either systemically, affecting the entire body, or involve medical skin care such as topical treatments.

Mild or limited psoriasis may be controlled with topical corticosteroids and emollients. Severe psoriasis may require treatment by light therapy combined with drugs.

Alternative therapies can be helpful in reducing symptoms, although they are most appropriate for milder psoriasis. Common alternative therapies include aloe vera, fish oil, and Oregon grape.

Consult your MD Now provider to determine which type of medical skin care might be most effective for you.

What is the Best Acne Treatment?

In most cases, acne is triggered by the hormonal fluctuations experienced by teens, although adults can also experience it. In all, about 17 million Americans have acne, making it one of the most common skin conditions, regardless of age.

Without treatment, acne can leave permanent scars. Your doctor will examine you to identify the type, before recommending acne treatment. In general, acne is either noninflammatory or inflammatory.

Subtypes Include:

  • Blackheads
  • Whiteheads
  • Papules
  • Pustules
  • Nodules
  • Cysts

Since some people experience a combination of acne types, your MD Now provider will recommend medical skin care based on the type or types of acne diagnosed.

How Do You Know What Skin Care Treatment You Need?

Your MD Now provider will work with you to determine the best type of medical skin care based on an examination of your skin and by asking questions about your symptoms. Although most rashes clear up quickly, others may require long-term treatment, such as medicated ointments, creams, and shampoos.
