No. Nothing to see. It just felt like a bruised tailbone on and off for a few months and then one day there was a large hot lump that felt like a large acne spot type thing just to the left of the tailbone. I could feel it but it wasn’t visible to the eye. No head or anything and just a bit sore.
I went to the GP who diagnosed it as Pilonidal Sinus (‘nest of hair’ - lovely), gave me antiseptic cream and oral antibiotics and told me to come back in a week. Didn’t say anything about drainage or removal.
After a week it was the same but ached more (some people say they are very painful but mine wasn’t) so I was referred straight to the hospital to have it drained. I thought it would be a day job but no, It was a general anaesthetic and a long aftercare program of salt baths and packing with gauze and iodine with the district nurse and later at the local health centre.
I couldn’t see the wound, obviously, but the nurse described it to me as being the size and depth of a large hen’s egg. It took about eighteen months before the last dressing came off and decades on, as I said, I’ve had no re occurrence but still have an awkward scar.
It all sounds quite drastic - and it was - but it was clearly what needed to be done. I’ve met others (its much more common in men) since then who can’t get rid as they can’t clear the infection due to not getting effective enough treatment.
The infection can make you feel quite rotten generally, you just don’t realise it at the time.
Having said all that I hope you DP’s problem is not as severe and more easily solved, but please tell him not to ignore it if any treatments he is given are not working, it won’t get better on its own.
