I understand your concern regarding your skin problem and I hope I am able to help you in the same.
Now I have seen the attached picture.
You seem to be having neurodermatitis
which is a type of eczema of the skin.
Such lesions are very common over the scrotum.
These are associated with severe itching
First of all what you need to do is to try and avoid itching. Itching tends to increase this type of eczema, so you should avoid scratching the area as much as possible.
Apply a topical cream like candid
b cream over it twice a day for a week.
Take tablet levocetrizine once a day along.
Take this treatment for one week.
I am sure it will help.
