I am so sorry! How awful! The only thing that gives me a little relief is eating raw foods, avoiding meat and bread. There are chinese herbs one can buy that help but i have yet to have found anything to completely get rid of them. It's a hard area to take care of as things are constantly exiting...
If you are strong enough, I would suggest a juice fast for as long as you can. I managed to do this for 5 days and it helped greatly, however intend to try to do at least two weeks, preferably more. in order for that area to heal, you have to give it a break. lots of greens, celery, ginger etc.
Fargelin is the chinese herb that you could probably find on ebay. cayenne pepper drinks are hard but help with circulation...and cayenne pepper enemas...are also hard but it only urns for about 20 minutes.
I hope your operation went well and you are suffering less.
