So many things can turn your skin red (or tan, if you’re darker). Here’s a follow up list of possible causes to that new patch:
An oval shaped rash that follows a head cold or sinus infection?
This is a mild rash called pityriasis rosea, and it might be caused by a virus (there’s evidence but no confirmation). The oval rash will spread (usually along the torso, sometimes the groin) and last for months.
Cause is tied to two things: gyms, and a weakened immune system. If you get a positive diagnosis, some research has found that sunlight may help the rash clear up.
All over red patch, possibly with welts:
This might be a sign of an allergic reaction. Watch for further symptoms, especially closing of your airways, as well as swelling, and see a medical professional right away if symptoms get worse. Otherwise, avoid the suspected allergen until you can have it confirmed.
Another itchy, red patch
Probably eczema. Eczema is actually a broad term for a number of rashes that cause itching and redness. Many people experience eczema during childhood, but there are a host of other forms that can affect you in adulthood.
Some forms can peel, crack, etc. Moisturize, be gentle with it (some people with eczema can get irritated easily). Eczema can be hard to get rid of—you need to employ both prevention and treatment rigorously.
If you’re told you have eczema, there are a number of things you can try:
-Oatmeal soothes itching. Ground up fine, you can put it in a bath, not ground up you can use a tea bag. Or make a paste to rub the irritated spot.
-Avoid irritants like citrus, garlic/leek/onions, and certain plants. What makes eczema worse will vary between people.
-Keep your skin hydrated, and use only very gentle ingredients (go all natural).
