A message from HS Voices Connect Japan
HS symptoms are often not visible to others, and pain or drainage can be difficult to discuss.
Some people struggle alone for a long time, believing that recurring boils are simply normal for them.
We hope this seminar helps people learn about HS and consider discussing their symptoms with a dermatologist.
Patients, family members, friends and anyone interested in HS are welcome.
If you are in an area affected by the earthquake, please prioritize your safety and daily needs over attending or watching the seminar.
This event is organized by NOTRD, not HS Voices Connect Japan. This article reflects information available at publication. Check the organizer's website for current event and participation details, and official authorities for current earthquake information.

Understanding hidradenitis suppurativa
Hidradenitis suppurativa (HS) is a chronic skin condition with recurring painful lumps and drainage.
What is HS?
It often begins after puberty. Overseas estimates suggest about 1 in 100–200 people may be affected. HS can affect people of any gender and may persist for years.
This estimate is based on overseas data.
What happens?
Inflammation develops around hair follicles, causing recurring pain and drainage. Tunnels under the skin and scars may develop.
How is it treated?
Treatment may include topical medicines, tablets or injections. Starting treatment early can help limit progression and improve quality of life.
Do these symptoms sound familiar?
- Recurring boils in the armpits, groin, buttocks or under the breasts
- Painful lumps that may drain pus
- Pain when walking or sitting
- Symptoms that return in the same place
If boils keep returning, speak to a dermatologist early.
Living with HS
- Seek diagnosis and treatment.
- Continue treatment suited to your symptoms.
- Discuss lifestyle and weight management.
- Work with your healthcare team.
