Hi
Welcome to the MedHelp forum!
This looks like urticaria or hives. The swellings or wheals produced after itching can be pale (of skin color) or red. Urticaria is usually triggered by allergens, such as drugs, foods, insect bites, inhaled substances, in response to sunlight, cold, heat, stress, exercise, or a viral infection. Other common allergens are pollen, mold, dust, pet dander, or cosmetics. Since you experienced an itch, just go over these possibilities in your mind. Something may strike you. In many cases, hives clear up themselves and don’t require diagnosis or treatment. However if they persists you may need to see a specialist called an allergist to determine what is causing the reaction. Please let me know if there is any thing else and do keep me posted. Take care!
maybe this is my problem too ... i need answers also
You need to take a benedryl so you don't itch and make them spread. It probably is a rash from something you are allergic to like poison ivy or something else. Keep up with the caladryl and you may want to try aloe very gel. witch hazel, and an oatmeal bath. You need to be diligent about using these things. If these don't work I would recommend you see a doctor.
