What could cause a red, bumpy, itchy rash on the extremities?

Hi,

Welcome to icliniq.com.

I understand your concern.

Atopic dermatitis is an endogenous eczema (eczema due to internal causes) characterized by extreme itchiness and recurrent symmetric eczematous dermatitis. The involvement of a site depends on the age of the patients. This chronic eczema is one of the atopic conditions, and together with asthma and hay fever, it has a heritable tendency. Certain environmental factors like winter inhaled allergens, and certain food may aggravate this disease in a certain subset of patients. Its clinical course and features vary with age and are easily aggravated by secondary infections.

I suggest you practice these general measures:

1. Avoid triggering factors that provoke itching.

2. Avoid irritants that may trigger itching, like woolen clothes, chemicals, etc.

3. Avoid excessive cleaning or degreasing of the skin and use mild soaps or cleaning lotions.

4. Avoidance measures include reduced contact with house dust mites using barriers on mattresses and quilts, thorough and regular vacuuming of rooms, avoiding the use of carpets, and use of anti-mite sprays.

5. Moisturizers are used to alleviate the itching due to dry skin. Emollients can be added to the bath or applied directly to the skin.

6. Topical steroids are used for localized exudative lesions and sometimes in combination with topical or systemic antibiotics to prevent secondary infections like Clobetasole or Beclomethasone.

7. Systemic antibiotics are used in patients with extensive infected lesions.

8. Systemic steroids can be taken but that too under dermatologist supervision.

9. Take antihistamines like Levocetirizine tablets 10 mg once in the morning and the evening.

I hope this helps you.

Revert in case of queries.

Regards.
