Hi, thanks for using Healthcare Magic. Many skin conditions described by so many sign and symptoms. Rash can arise from allergy, irritation, even inflammation. But you maybe have allergic rash, so I suggest you to do some skin allergy test which is a method for medical diagnosis of allergies that attempts to provoke a small, controlled, allergic response. For now: 1. Apply a cold, wet cloth or ice pack to the skin that itches. 2. Take a shower 3. Moisturize your skin with aloe vera 4. Apply cooling agents, such as menthol or calamine But the most important, avoiding the allergen that may cause this condition like dirt, cold weather, pollen, etc. Take care, dr. Nurul
