Skin Discoloration

Hello,

The link --> https://s14.postimg.org/hpc1y07ld/20170604 _015939.jpg is a photo of a patch of skin I never had before. I noticed it after returning from the Philippines. The rash is located on my right side, it is not itchy but it feels rough/dry to touch. I went to the my doctor more than two weeks ago, he prescribed Lotrisone because to him it seemed like ringworm. I heard that ringworm is contagious, spreads via skin to skin contact and itchy. My rash does not seem to have those characteristics. I have applied Lotrisone for more than two weeks without any changes.

If anyone has seen this type of rash before or has any information, please let me know. Thank you.
