Frequently Asked Questions

Finding the right care for HS can be a long journey. We are here to provide the answers, advanced treatments, and compassionate support you need to manage your symptoms and improve your quality of life. Explore our most common patient inquiries below.

Is HS contagious?

No, HS is not contagious. It cannot be spread through skin-to-skin contact, sharing personal items, or any other form of physical interaction. It is caused by an overactive immune response and follicular blockages.
Surgery is often recommended for advanced stages (Stage II or III) where “tunnels” or deep scarring have formed. We offer specialized procedures like “deroofing” and excision to provide long-term relief in specific areas.
For immediate relief at home, warm compresses and loose-fitting clothing can help. If the pain is severe or a new abscess appears, contact our office immediately so we can adjust your treatment or perform an in-office drainage if necessary.
There is no cure, but HS can be effectively managed with the right treatment plan and ongoing care.
Yes, most medical treatments and many surgical procedures for HS are covered by major insurance providers. Our team will work with you to verify benefits and assist with any necessary prior authorizations for specialized medications.
We offer a 50% Prompt-Pay Discount for self-pay patients. We also accept CareCredit, a healthcare credit card designed to help you pay for out-of-pocket medical expenses.
HS is NOT an infection; It is not the patient’s fault, nor is it a result of their hygiene or lifestyle choices – HS arises from a combination of factors, many of which are uncontrollable, such as genetics.
Although patients may experience many similar symptoms, each case of HS requires a unique and personalized treatment plan, whether it be medical options or surgical surgical procedures.

Follow up depends on severity, but regular visits help monitor progress and adjust treatment as needed.
