Without examination confirming a diagnosis is tough but these symptoms can be due to ring worms or contact irritant dermatitis.
Ringworm is a fungal skin infection that occurs on the face, body or scalp. The symptoms of Ringworm or Tinea Capitis include a dry itchy scalp, scaling, crusting, inflamed nodules, hair loss and tender enlarged lymph nodes on the neck. Because of the scratching that is involved with the condition it can become secondarily infected with a bacterial infection.
Contact dermatitis is a skin reaction resulting from exposure to allergens (allergic contact dermatitis) or irritants (irritant contact dermatitis).
Take some over the counter antihistaminic like benadryl or Claritin for some days.Also apply mild steroid cream and calamine on the itchy areas.If symptoms become severe,then pls consult a dermatologist to rule out ring worms as treatment for ring worms is entirely different.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.
