These itchy bumps can be due to lichenoid dermatitis or scabies. Scabies is an infestation of the skin with the Sarcoptes scabiei mite. It is characterized by intense itching, usually at night and by small insect-type bites lesions on the skin. Diagnosis of scabies is made by scraping the skin and viewing the material under a microscope to see the characteristic mite or eggs.
I suggest you to consult a dermatologist and get these two possibilities evaluated.
