..also called lichen urticatus. It is a hypersentisive reaction to insects like bedbug.there may be papular eruptions on extremities. There may be mild to severe pruritus
.Antihistaminics like levocetirizine
may be taken till itch is relieved.steroids in tappering dose may be taken. Apply mild steroid cream on lesions.
Avoid stress and worries. Avoid soap bath. You may use dettol in water for bath.
I feel , you may be improved. Still, you consult dermatologist
I hope you got my answer.
