[|Human|] Hi. The last day I ve noticed a really painful lump around an inch down from the start of my bum crack. Walking and standing is no pain at all but sitting down or lying down is unbearable.I noticed the lump first appear a couple of month ago in the same place but that time it was only painful to touch and cleared within a few days. However this time round is much worse.
[|AI|]  Hi, Dear,Thanks for the query to Chat Doctor. I studied your query in depth. I feel concerned about it. In my opinion you are suffering from-Pilonidal cystitis, which has recurred after a couple of months./ or may be recurring boil, which occurs due to friction in that area. I would advise to take-a-Tb NSAID, b-Antibiotics, if it relieves(then its-acute on chronic-boil)It's ok. If it does not regress fully, then-USG / Histogram/X-ray of buttocks, would fix the colonial sinus. If colonial is there-then it would need surgery at hands of ER surgeon. Please take treatment on these lines, which would be best decided by your Surgeon. . Hope this would solve your query. Please contact again, and I would love to attend your queries promptly. Have a good time.
