Q.
Skin on Fire? Why Dermatitis Attacks & Medically Approved Relief
A.
A burning, itchy rash is often dermatitis, driven by inflammation when irritants, allergens, or an overactive immune response weaken the skin barrier and sensitize nerves. Relief usually comes from avoiding triggers, repairing the barrier with regular fragrance free moisturizers, and using doctor approved treatments like topical steroids or non steroid creams, with wet wraps or nighttime antihistamines for tougher flares; urgent care is needed for signs of infection, rapidly spreading rash, severe swelling, or breathing problems. There are several factors to consider that can change your next steps, so see the complete details below.

Q.
Skin on Fire? Why Poison Ivy Triggers That Electric Itch & Medically Approved Next Steps
A.
Poison ivy’s urushiol oil triggers an allergic skin reaction that can start 12 to 48 hours after contact, causing an electric itch with redness, swelling, and line-like blisters; once the oil is washed off, the rash itself is not contagious. Wash exposed skin and gear promptly, then use cool compresses, calamine, colloidal oatmeal, and early 1% hydrocortisone; seek care for widespread rash, face or genital involvement, severe swelling, signs of infection, lasting symptoms beyond 2 to 3 weeks, or any trouble breathing. There are several factors to consider for treatment and prevention that may affect your next steps; see complete details below.

Q.
Skin on Fire? Why Your Body is Reacting & Medically Approved Contact Dermatitis Relief
A.
Burning, stinging, or itchy skin after touching something is often contact dermatitis, triggered by irritants like soaps and sanitizers or allergens like nickel, fragrances, latex, hair dye, and poison ivy, and it typically appears where contact occurred and improves when the trigger is removed; see below for other look‑alike conditions and how to confirm. Medically approved relief includes stopping exposure, gentle washing, fragrance free thick moisturizers, short courses of 1 percent hydrocortisone, cool compresses, and antihistamines for itch, while moderate to severe or persistent cases may need prescription steroids or patch testing, and urgent red flags like face or throat swelling, breathing trouble, spreading infection, or no improvement in 1 to 2 weeks require prompt care, with full guidance on next steps below.
