The primary diagnosis of allergy rash can be discovered through clinical evaluation. A thorough examination of your medical history can reveal information about the irritating agent. Patch testing can also identify the source of allergic contact.
A patch test involves the application of adhesive patches to your skin. Chemicals in the patches have been linked to allergic responses in the past. Your healthcare professional will examine your skin for 48 hours. Your provider will re-examine your skin after 48-96 hours.
It is difficult to resist scratching the itchy affected area. Nevertheless, you need to stop yourself from scratching it as this can further irritate your rash. Moreover, the itching and swelling can be relieved through OTC medications and home remedies, like:
- Cream containing hydrocortisone
- Calamine lotion and other ointments
- compresses à Froid
- Oatmeal baths
Discuss treatment choices with your doctor for your particular rash. Moreover, it is also better to figure out what causes your rash so that you can avoid it.
