Hello... My brother has Chron, and recently he had his perianal abscess drained. His abscess is healing, but his GI told him that it could very likely be fistula, and scheduled him for a MR and also put him on some sort of an antibiotic. She told him that if it shows it is fistula, she we will put him on a biological medication. However he is terrified of biological medication and it's side effects. Did anyone of you try some alternative medication before using biologic ones. Did it do you any good?
