Thank you for your query.
As you have not mentioned from when the spots are present I presume they are of recent origin. As there has been no change by your application of lotion, antiungal and neosporin
creams I suggest that you get it examined by a doctor who will guide you with the correct course of action to be taken in the case. It is very difficult to tell what it is and what remedy be given.
I hope I have answered your query to your satisfaction.
