Hi, 2 months back I underwent a laser surgery for pilonidal sinus.Doctor performed PILONIDAL SINUS EXPLORATION+Laser ablation of sinus tract. The finding was short pilonidal sinus tract with absence of hairs and ineffective tissue. After that surgery , I was fine without any pain.but since 2 days onwards I'm getting pain in the same place. But There is no discharge from that.only pain is getting increased.what could be the reason? Is this is the reaccurance of pilonidal sinus? If it is what should be the treatment? Plz suggest
