Thanks for writing in.
The condition you are suffering can be phrynoderma or xerotic dermatitis
It is caused by nutritional deficiency
Usually vitamin A
,E and Fatty acid deficiency causes it.
You can take tab zyrtec for itching.
Apply aloe vera
lotion twice daily.
Oral vit A E would be helpful.
Hope this helps.
Wishing you good health.
