It seems that you might have irritant contact dermatitis
due to some local application like betadine or some other which you have not mentioned.
There may be mild bacterial infection also.
Take antihistaminic like levocetirizine
till itching is relieved.
Take oral antibiotics
Apply antibiotic like sisomycine.
I think you may get good result in few days. However, you may cosult nearby dermatologist
I hope you got my answer.
