hi..thanks for the query
From what you describe, you might be suffering from foot eczema
.You can follow the following steps:
1) Use ample emollients or medicated moisturizer multiple times in a day to keep the area moist and hydrated.
2) Use only pure cotton socks
3)Have oral anti-histaminics like Tab.Allerga to relieve the itch.It is important not to scratch.
may be required in your case.These relieve the itch and reduce the eczema pathology.
It is important to remember that the lesions are recurrent and it is important to do follow ups for reviewing treatments from time to time with your dermatologist
Hope this helps..Take care
