. Take some oral antihistaminics like Benadryl (cause drowsiness) or Claritin and apply calamine lotion as it helps in soothing the skin. You can also apply a mild steroid cream and if the symptoms persist then consult a dermatologist as oral steroids may be needed.
I hope it helps. Take care and please do keep me posted on how you are doing or if you have any additional doubts. Kind regards.
