Can you screen for the disease?



What are the methods of diagnosis?

Diagnosis is made by examination and investigation. As infection is not the cause, there is no specific bacteria to look for. Certain questions would need to be answered, such as family history, frequency of recurrent lesions, location of lesions, etc.

Swabs or biopsy may be taken, and although they normally appear clear, it is necessary to eliminate other diseases or causes, and although HS itself is not an infection, secondary infections may occur due to open wounds and lesions being prevalent.

How can it be treated?

Unfortunately there is no cure, but ongoing treatment is possible to help control any flaring lesions. A variety of medication is available, however there is no specific treatment for everyone, so trial and error is the way to go.
