Hi dr, my testicals and area around that are dark & itching. its been for an year now. i feel it may be a fungus infection. any advice/medications?

Antifungal creams: It could be jock itch. Most "jock-itch" is a superficial fungal infection of the skin in the groin area. If this is the case, many athlete's foot remedies will work here as well. The ones to try first are lotrimin ultra or Lamisil (terbinafine) cream. If it is because of yeast infection, use Nystatin cream.

Intertrigo: Intertrigo is an inflammatory condition of skin folds, induced or aggravated by heat, moisture, maceration, friction, and lack of air circulation. Intertrigo frequently is worsened or colonized by infection, which most commonly is candidal but also may be bacterial, fungal, or viral. Intertrigo commonly affects the axilla, perineum, inframammary creases, and abdominal folds. Rx vytone cream 1%.
