After taking homeopathy medicine, how can I come to know that the fistula is gone or the canal has reduced. My doc has asked me to remove an mri again. It's kind off costly and i'm not financially that good. When I removed the first mri about 3 months back it showed as 8 cms. Is there a way to know that it's healed. Because I can still feel the canal or its the nerve I don't understand. When I press besides the anus I can feel the long and stiff nerve like something. But it's not on the other side of the anus. Pls, help. My doc said that only we can know with the mri. As she needs to know how much it's gone down to continue with the medicines as there lots of improvement den before.
