Hi, Welcome to HealthcareMagic Forum.
Do you have any past History of Allergies or asthma in you or your Family?? You are having Atopic Dermatitis which causes scaly and itchy rashes, it occurs due to a hypersensitivity reaction in the skin. It can get worsened by allergies, exposure to animal fur, pollen, flu, dry skin, contact with rough materials, cold water or stress. Get yourself examined by a Dermatologist so that he may examine you and if possible take a skin lesion swab for biopsy to confirm it or do a allergy testing. TO relieve your itching, you can use cold compresses. Try to identify and avoid triggers that worsen the itching or increase the size of rash, Avoid scratching, moisturize your skin and use a humidifier at home and if possible remove the pets with fur from your home and wear cotton clothing. Exercise regularly and eat healthy nutritious balanced diet which should include fresh fruits and green leafy veggies.

Wish you Good Health, Take Care.
