Rash 'again' in 'new' area

I live in a climate where 'sweating' is an olympic sport of its own ...in the recent past had a 'rash' that P.A. (couldn't see dermatologist-handles now only cancer-related situations-in process of finding new doctor)  who thought the  existing 'whatever' was a fungus+ -prescribed Alcortin bid + Zeabsorbe-use till  rash is 'gone' ... it worked .
       now i have the same burning (non-itching) situation at the bottom of my back, in 'crack' between buttocks that i do try to keep 'dry'...not always accomplished !  
       I was thinking of using the remaining unopened packets of Alcortin and following the same procedudre ... I'm sure  Alcortin is nothing to 'play around' lightly but until i find another doctor could i try to repeat the same regime as in the recent past ?   thank you in advance ..

Hi,
This could be a fungal infection or an eczema. A warm, damp environment greatly contributes to the fungus  cultivating in skin folds especially with tight, sweaty or rubbing clothing.

Affected areas may appear red, tan, or brown, with flaking, rippling, peeling, or cracking skin associated with an itching or a burning sensation.
The treatment would be with anti-fungal creams containing tolnaftate, clotrimazole or miconazole to be applied on the affected areas.

Eczema  is a form of dermatitis, or inflammation of the upper layers of the skin. The term eczema is broadly applied to a range of persistent skin conditions. These include dryness and recurring skin rashes which are characterized by one or more of these symptoms: redness, skin edema (swelling), itching and dryness, crusting, flaking, blistering, cracking etc.

Treatment is with glucocorticoid (a corticosteroid steroid) ointments, creams or lotions. They do not cure eczema, but are highly effective in controlling or suppressing symptoms in most cases.

Since Alcortin contains anti-bacterial, anti-fungal as well as steroid medications it would be safe to use this to treat the condition with this.
