What are the treatments for this pilonidal sinus?

Applying warm compresses several times a day, keeping the area clean with soap and water, and avoiding piercing or squeezing the affected area can help with a pilonidal sinus. If you do not see any improvement or experience worsening symptoms, such as increased swelling, redness, pain, or fever, it is important to consult a doctor. It may also be beneficial to consider using a donut-shaped cushion to help alleviate pressure on the area if sitting for long periods aggravates the condition.
