Hi,
The presence of this rash may suggest a fungal infection, a contact or allergic dermatitis, and folliculitis.
The redness and itchiness may highly suggest a dermatitis or fungal infection.Weather increases moisture and sweat in the area which may irritate the skin and consequently enable the growth of involved organisms. The heat may cause subsequent irritation which may lead to redness, itchiness, scratching and consequent excoriations.
I suggest that you seek consult with your primary physician so that this may be properly assessed .You may be needing topical medications as maintenance therapy.
Hi, I have the same problem if you find any thing. Thanks.
