<s>[INST] I had a pilonidal cyst about 1 year ago. The cyst became very painful and I went to my doctor. My doctor sent me to a surgeon to have it opened and drained. This solved for a while the problem, now I have noticed it came back, only this time it tends to open and drain on its own. It drains quite often and has me a bit concerned. should I have it looked at? [/INST] Hi, thanks for sharing your health concerns with Chat Doctor!  I have gone through your sufferings and I can understand the recurrent problem you face! I must say that the previous surgery was not complete due to some technical region / local perineal approach problem or could be some post-operative infections too! Might be some leftover granulomas/foreign body materials/contamination or inadequate post-operative care... And yes, you need more treatment possibly a re-surgery with more time and more planning! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
