It can be folliculitis
,CBDC, papular urticaria,etc.
You can apply Calamine lotion over the affected area.It is cooling and soothing lotion.It will relieve itching.Also you can take tablet Zyrtec for itching.
Oral and topical antibiotic
can be helpful.
Also I encourage you to visit a dermatologist
or physician for proper diagnosis and treatment.
Hope this helps.
