You have mild psoriasis – which is a common skin condition. Signs may include red scaly patches that can itch or burn. The causes are not entirely known but are believed to be connected with the immune system. To help control your symptoms, try using moisturizers more frequently; also stay away from any known irritants if possible. If you have access to the sun, try getting some sunlight in affected areas. You can also visit a dermatologist to treat this condition.
