Re: Persistent red rash on cheeks, what is it?
If you suspect Rosacea or Lupus, you'll need to see a doctor to rule them out.
I have very sensitive skin too, and it doesn't take much to turn my face red. Deodorant soap, blow-drying my hair in a hot bathroom, going out in the cold, stress, acne cream, wrinkle cream, whatever. Even some B-vitamins can cause a red flush. Dermatologists always recommend Cetaphil lotion for cleansing, and a moisturizer made for sensitive skin.
Most people with sinus allergies tend to have dark circles under their eyes. The delicate undereye skin can get red or irritated by makeup.
I don't know if any of those other symptoms are related. Many women get cold and tingly hands and feet, and when you get a physical exam from the doctor, it should include routine tests for thyroid and diabetes. Read about carpel tunnel syndrome and do some simple exercises to prevent it.
