Dermatology Questions? Ask an Online Dermatologist.
Was the sample from the skin cultured? Did you have skin biopsy? How tall are you? How much do you weigh? Can you attach the photos here? Pain or itch? Any medical problem? Any surgeries? Any other medications? Any family medical history? Does anyone around you have similar problem?
Can you attach the photos here?
The skin looks almost okay. It could be allergic reaction to lotrimin af spray. But it could be Erythrasma (bacteria infection called C. minutissimum). To exclude fungal infection and Erythrasma at first, the skin sample should be examined under the microscope for fungal infection and the skin should be examined with a Wood's lamp for Erythrasma. If it is negative, you should try to use 1% hydrocortisone cream.
If it is Erythrasma, topical clarithromycin or erythromycin is effective. But neosprine would not help. In addition, if it is fungal infection, it should be avoided because antibiotics make fungus grow.
