Question and answer
Hidradenitis suppurativa often causes complications when the disease is persistent and severe. These complications include:
- Scars and skin changes. Severe hidradenitis suppurativa may leave rope-like scars, pitted skin or patches of skin that are darker than normal.
- Restricted movement. Open sores and scar tissue may cause limited or painful movement, especially when the disease affects the armpits or thighs.
- Obstructed lymph drainage. The most common sites for hidradenitis suppurativa also contain many lymph nodes. Scar tissue can interfere with the lymph drainage system, which may result in swelling in the arms, legs or genitals.
- Social isolation. The location, drainage and odor of the sores — singly or in combination — can cause embarrassment and reluctance to go out in public, leading to depression.
