The presence of a rash in the private area can be caused by an irritation of the skin caused by several factors, as stated by WebMD. A rash can occur without showing any symptoms, and it can clear up while using home treatment measures. If the condition persists or worsens, an individual should consider visiting a doctor for a diagnosis.
A rash in the private area may occur due to an allergic reaction to soaps, shampoos, detergents and perfumes. This leads to a condition known as contact dermatitis. Rashes caused by dermatitis tend to be itchy, but they are rarely serious. Avoiding the use of certain products can help in preventing contact dermatitis.
Rashes in the private area may also be caused by other factors, including balanitis, reiter syndrome, lichen planus, yeast infection, psoriasis, pubic lice and scabies. Sexually transmitted infection that can also cause rashes include syphilis, genital herpes and genital warts, as stated by Healthline. A particular cause for a rash may only be determined after a doctor's checkup.
The treatment of a rash depends on the underlying condition. Some may need prescription drugs while others can clear it up with the use of home treatment methods. Seeking the attention of a doctor prior to using any treatment method is necessary.
