Hi... You may have to avoid the allergens to prevent itching.. That may be the only solultion.. Multivitamin supplements either in the form of dietary source or through medical drugs will also help you.. I have been on multivitamins since last 6 to 8 months. You may not get gelp immediately but over a period of time you can see some help from it.. Get an allergen test to know the if any is causing your symptoms and avoid those too..
