Although HS can occur anywhere FPSus are present, lesions typically present in the axillary, perineal, perianal, groin, and inframammary regions. Prevalence of HS is estimated to range from around 1% to 4% globally, although the actual prevalence may be higher due to under-reporting and misdiagnosis. The average length of time to diagnosis is 7 years, and some individuals live with HS for 12 years or more before they receive a diagnosis. When not treated properly, HS can worsen as more nodules form, and the recurrence of lesions leads to abscesses, tracts, strong odor, and scarring. Patients may suffer from chronic pain and impaired mobility, and the lymphatic obstruction can lead to peripheral lymphedema. In addition to the physical burden of disease, individuals with HS may all have psychosocial complications, such as depression, social isolation and decreased relationship satisfaction with family and friends, and decreased work productivity.
