I Am 40 Yrs Healthy Male, Had Some White Spotings

I am 40 yrs healthy male, had some white spotings on skin (arms, shoulder and thighs). I was advised medicine for fungal infection which i completed and doctors confirmed that there can not be any fungal infection left after medication.. Still at times the spots get extra white. I am advised ow for DICARIS for worms. I took, has very slight itching. Pls advice.
