It is important for you to understand that you have to stop this "itch scratch" cycle.When you have itch,you scratch and this inturn aggravates your lesion and when you see increasing lesion,you feel more itch and then scratch and this aggravates the lesion.As you have specified you are having "Neurodermatitis".
The main stay of treatment is steroid
creams with anti histaminic tablets. If the lesions are infected then a course of antibiotic will be needed.Sometimes anti anxiety
drugs are also useful. Once the lesions heals take good care of the skin and moisturize regularly so that you dont have any itching.
The main step for you to do is 'stop scatching'.
Hope it helps,
