[|Human|] I had a pilonidal cyst/sinus excised a few years ago and now I am experiencing similar pains to those which I felt previously. There is very little to see though (only 2 very small pimple like things) although the pain had been quite severe at times (similar to the level I experience when it was infected prior to my original op). Is it possible for the sinus to recur in this hidden fashion with little or no visible signs on the surface?
[|AI|]  Hello As you mentioned that few years ago you got surgery (excision) . Colonial sinus a sheaf of hairs and usually recurrence is possible if not excised properly. As you mentioned that there are two holes (actually these small holes are opening of colonial sinus) , so in my opinion consult another surgeon and get his opinion. However, in colonial sinus surgery is only an option. Since this is a sheaf of hairs so in my opinion laser is not so effective option. Open surgery is the best treatment. Till take painkillers.
