The hole left from my surgery was about the size of a golf ball and once the drainer guaze was removed it was left open to heal itself.
Geez, that must really be terrible! I understand about the wound, because it's like what Atreides has. His was about an inch deep, 5 inches long and 3 inches high. It's just terrible.
What seems to accelerate the healing process (the doctor was impressed last time he saw Atreides -but of course, we couldn't tell him about it because he's against "unofficial treatments"-) is to use a special product (it is like artificial fibrin made from seaweed, and can be found at the pharmacy) soaked in a 25% DMSO-75% coloidal silver solution. The DMSO in particular seems to make a great difference.
The, at least one long shower a day, and scrubbing all the skin seems to be preventing other cysts from growing.
I have never heard of the filling you mentioned. Did they say what this is for? This problem can cause tunnels to other areas and does not always start in the same location so I'm wondering if the filling is something that should be done.
We downloaded a few papers about it, which I can send to you and anybody else who is interested. The technique is quite new. But it depends on where the fistula is. I don't know where yours were, but when you have an anal fistula, it won't heal by itself, and there is a high risk of it developing more and more branches, and it you don't catch it in time, there is a chance that the doctor will have to cut your sphincters. With this method, there is only a 20% recurrence and no "butcher job" at all. They put a thread on the fistula, and you have to let it drain for about 8 weeks. Then, they remove the thread and either glue it with a medical "super glue" or with your own natural fibrin extracted from your blood (the centrifuge it). So, we are hoping that this will be the very last time.
But for smaller ones, it's better, I think, to do the showers, the scrubbing, aspirin and DMSO. But as far as I know, if they get very big, sometimes there is no other option except for having it surgically removed. Hopefully, with all we are finding, that won't be necessary for anybody else.
Of course, it's still early to tell, but we DO have lots of hope, and I sincerely hope that all the information you are finding here will help you. It is really good that you know it's not your fault, and that although it was extremely hard for your mind, you can change that. The diet helps a lot with that, for sure. It is as if the more you learn about everything, the stronger your body becomes.
