Pilonidal Sinus Surgery scar still inflated with some sort of fluid? - pilonidal sinus more condition_symptoms

As the title suggests, it was made in July 2007, from 4-6 weeks later and now 2 years later, the scar is completely healed, I have no pain, but the scar area which is located between the neck near the tailbone is still so swollen with fluid, and is almost unnoticeable in the handle. I thought that with time disappear, but I will not seek a procrastinator a doctor. Is this normal for this operation?
