Hello It’s not an infection or a blood disorder. No evidence of internal illness if bloods are normal. It could be: Keratosis Pilaris: Common, benign skin condition. Pinpoint, rough papules (often on thighs, arms). Worse in dry weather or with poor moisturization. Not itchy or painful usually. Chronic Folliculitis or Heat Rash (Miliaria): Mild inflammation of hair follicles, may wax and wane. Triggered by heat, sweat, tight clothing, or dryness. Non-specific Dermatitis or Hypersensitivity Rash: Could be due to detergents, soaps, clothing materials. Often poorly responsive to steroids unless allergen is avoided. Food-related or contact urticaria (Atypical presentation): Recurrent pinpoint rashes, usually itchy. May have no consistent lab findings.

First show to Dermatologist instead of online consultation

Pinpoint rashes persisting for over a year without systemic symptoms and not responding to steroids may indicate a non-allergic, possibly vascular or hematological cause. Common possibilities include petechiae, which could be due to low platelet count, vascular fragility, or rare dermatological conditions like pigmented purpura or chronic urticaria variants. Since steroids have shown no improvement, this is unlikely to be an allergic or autoimmune rash

Kindly consult once physically to nearby pediatrician once again

With all due respect, online consultation won't be helpful. Kindly consult a pediatric hemato-oncologist or a pediatric rheumatologist for further evaluation and management
