Allergy. This could represent allergic reaction to material that touched skin. Try cold compress and hydrocrtisone cream. If it does not help may need to see doctor for evaluation and treatment.
Semetrical, red, VERY itchy small bumps on my elbows. When I scatch, they bleed. The itchiness doesnt stop throughout the day. Since 4 days ago.
Dry skin? Apply moisturizer at the area at least 2x daily especially after bathing. Topical hydrocortisone cream for a few days may help. If problem persists, see dermatologist.
