The tiny itchy bumps all over the body are most likely urticaria (hives) from a food or environmental allergen. This is common and usually resolves on its own within 24-48 hours, but an antihistamine can help relieve the itching faster. Avoid the suspected food trigger and any new soaps or products you may have used recently.
Next Steps
Take an antihistamine and monitor â if the rash spreads to face, lips, or you have any breathing difficulty, go to emergency immediately. Please consult me directly on Practo for a detailed evaluation.
