Hi dear friend,
Yes! Homeopathy definetly offers a curative approach for anal fistulas. You are right that there is very little chance of a complete cure in other systems of medicine. My experience has been that patients with fistula often need medicines which affect suppuration and the constitutional medicine too. But there are too many medicines, some homeopaths only give constitutional remedies, others only give medicines known to have a therapeutic indication and some prefer to follow one with other. What u need can only be ascertained by a qualified homeopath after a full case taking. But I can assure you that homeopathy can provide you definate help. Find a good homeopath and start treatment at the earliest.
But do remember that fistulas don't heal very easily because of the constant trauma and bacterial infection. And even under right homeopathic treatment it may take many months before the healing is complete. But that dosen't mean you won't notice any change for weeks. Usually the patients are able to tell the difference within a few weeks. So be patient with your homeopath and take care.And i have already posted the answer of Anal fistula treatment with ayurveda so just search it out in our ISC.i hope it will also helps you.
