Thanks for writing to us.
Skin colored itchy bumps can be seen in contact dermatitis
, lichen nitidus
, scabies etc. In your case too it could be scabies. Itchy bumps in scabies typically occur in web spaces, wrist , arm, underarms, chest, abdomen, inner sides of legs etc. Treatment is single time overnight application of permethrin cream
I would advise that you meet a qualified dermatologist
to diagnose and offer you Treatment.
Hope that helped.
