My Dear
Welcome to this site!
I have noted your details and concerns.
From the description that you have given I think you are having
Pityriasis versicolor. This is a fungal skin condition that results in usually light colored or brownish patches scattered over trunk and sometimes
limbs and face.
To my patients, I advise the following and invariably the response is encouraging.
1 Check if there is any shortcoming in your hygiene because the condition is known to affect those who sweat a lot or the sweat does not evaporate because of synthetic garments
2 A broad spectrum anti fungal in the form of Flucanazole given as weekly doses of 400 mg for three weeks helps most patients
3 Local anti fungal preparations containing
Miconazole daily and with or without
Selenium Sulfide preparations used every week provide great help in early resolution
4 The condition takes several months, sometimes 4-6 months to clear up but almost always resolves without residual spots.
I believe these suggestions will put you on the road to recovery and we will soon learn about your recovery
Best wishes
