Thought I would post my experience, I have had a pionidal sinus for the past six years, not known though until around 10 months ago when it actually burst (save the gore)! I finally went to my doctor and explained this strange lump at the bottom of my back and the nasty stuff that was now coming out of it, she advised that it was a pionidal sinus and explianed the operation solution, which would be cutting it out and the healing by secondary intention and this could take some time to heal etc, etc! I asked to be refered to the hospital for a chat with a surgeon, got seen with in 1 month, which is good for NHS standards!! They confirmed again what the problem was and advised me of a new treatment which was being developed by a surgeon who has a particular interest in these, Fiberin Glue and he was based at my local hospital in Derby! Basically, they put you under general then scrape out the sinus and fill it and any tracts with the glue and it invloves being able to return to normal life almost straight away! I went in to hospital and had this done on 27th April, I returned to work on 5th May, 1 week later! So far so good, some scabbing and have 2 small stitches which will disolve in another week or so but I am really hoping that this will be cured!!
I feel for anyone who has this, it is soooo uncomfortable and makes you feel so self concious when it leaks and you are out and about!
Anyway, not sure if this is only available in the UK or not but lets hope it's the way forward!
