Thanks for writing your query.
After reading your post it seems that you are having allergic dermatitis
It can be related to some allergen present at your workplace only and not at home.
You can take antihistamine like Fexofenadine
120 mg once a day, in addition to topical application of steroid
You should also go for de-worming.
If the problem persists, get yourself clinically examined by a Dermatologist
I hope this is helpful to you.
