Red or White Raised Bumps: Causes, Diagnosis & Treatment

At Emirates Hospital, we understand that red or white raised bumps on the skin can be caused by allergic reactions, infections, inflammatory conditions, or clogged pores. These bumps may be itchy, painful, pus-filled, or dry, and identifying the cause early is essential for effective treatment.

Causes of Red or White Raised Bumps

Skin bumps can result from infections, immune responses, or skin irritants. Identifying the underlying cause helps determine the best treatment approach.

• Acne (Whiteheads, Pimples, or Cysts): Blocked pores due to excess oil, bacteria, or dead skin cells can lead to red or white bumps.
• Hives (Urticaria): Allergic reactions to food, medications, or environmental triggers can cause itchy red welts that appear and disappear.
• Folliculitis: Inflamed or infected hair follicles can lead to red or white bumps, sometimes filled with pus.
• Milia: Small white bumps caused by trapped keratin under the skin, commonly seen in newborns but also in adults.
• Keratosis Pilaris: Rough, small bumps on arms, thighs, or cheeks caused by keratin buildup in hair follicles.
• Bug Bites & Stings: Mosquitoes, bedbugs, or spiders can leave red, swollen bumps that may be itchy or painful.
• Viral or Bacterial Infections (Chickenpox, Molluscum Contagiosum, Impetigo): Infections that cause clusters of raised red or white lesions.

Diagnosis of Red or White Raised Bumps

A thorough examination helps determine the cause and severity of the skin bumps.

• Physical Examination & Medical History: Evaluates appearance, duration, and triggers of the bumps.
• Skin Swab or Biopsy: Identifies bacterial, viral, or fungal infections.
• Allergy Testing: Helps detect allergic reactions leading to hives or rashes.
• Blood Tests: Checks for underlying immune system disorders.

Treatment for Red or White Raised Bumps

Treatment focuses on relieving discomfort, reducing inflammation, and addressing underlying causes.

• Topical creams (antibiotics, antihistamines, or anti-inflammatory agents) help reduce redness, itching, and swelling.
• Oral medications (antihistamines or antibiotics) treat allergic reactions or infections.
• Moisturizers and skincare routines help manage keratosis pilaris and prevent dryness.
• Avoiding triggers (allergens, irritants, and harsh chemicals) helps prevent recurrence of skin bumps.
