I have swollen n itchy toes ...something like chilblains..what should u do to cure?

Depends on the cause: There are many types and causes of skin rashes that could cause itching. Several types of inflammatory conditions of the skin, allergic reactions, and sometimes bacterial, viral or fungal infections can cause rashes on the skin. Insect bites can also be the cause of a rash on the skin. Have it evaluated by a professional and get the appropriate treatment.

Stay warm and dry: Chilblains can be prevented by keeping your feet warm and dry. Sometimes Hydrocortisone 1% cream can be used if the skin is itchy and irratated. It is important to find a brand of socks that do not make your feet sweat because the moisture is problematic. A brand that i highly recommend is smartwool.
