These lesions or areas of inflammation can turn intocystsorboilsfilled withpusthat can leak or seep.
When these cysts or boils erupt, there may be a noticeable odor.
The pus smell comes from the bacteria that have been trapped under the skin inside the boil.

These bacteria, called anaerobic bacteria, live without oxygen and can thrive under the skin before they erupt.
Tunnels or sinus tracts under the skin can appear at the open wound after a cyst burst.
Sweat and bacteria become trapped in these tracts and cause infection andinflammation.

This can cause more pus and odor.
Over time, as these areas heal, they can become hardened or scarred.
Why Does Hidradenitis Suppurativa Smell?
HS begins as tender spots of inflammation that look like pimples or boils.
A typical painful nodule will last seven to 15 days.
During this time, the boil may erupt, creating painful deep abscesses, or holes.
The pus that erupts from the boil can be foul-smelling.Draining of the boilmay continue for days.
Where Does Hidradenitis Suppurativa Occur?
Common places where HS boils occur are the:
There are three stages of HS.
Other symptoms such as itching, fatigue, or discomfort in spots on the skin may be more common.
These boils erupt, causing pus to drain from the abscess, which can cause HS odor.
As these lesions heal, scar tissue can form.
Hurley stage 3: In stage 3, HS is widespread across the body.
Multiple tunnels can form under the skin as can recurrent abscesses and scar tissue.
Abscesses will continue to erupt and drain.
In severe cases, the interconnected scar tissue can cause disfiguration or problems with mobility.
Avoidsoapswith irritants and harsh chemicals to help reduce irritation.
Certain ingredients in products like antiperspirants are known irritants.
Deodorants that contain aluminum salts are known to aggravate HS.
Shaving can also irritate the skin due to the friction that occurs between the blade and the skin.
Avoiding shaving by trimming hair instead can help avoid this friction.
Preventing skin abrasions can help with HS skin health as well.
Being gentle with the skin while cleansing is important.
Avoid loofahs or other abrasive washing methods.
Finding cosmetics and lotions that are free of fragrance and chemicals can also help reduce irritation of the skin.
When boils do form and erupt, it’s important to care for the open wounds properly.
A healthcare provider can adjust medications or suggest new treatment options that may work for your situation.
Seeking help from a healthcare provider early on can help prevent excessive scarring and slow progression of the condition.
Treating body odor from HS requires proper treatment of the disease itself.
