Hello James, welcome to the forum. You've come to the right place to learn about treatment options for Hepatitis C, many very experienced people frequent this forum. Hopefully the treatment course that you just finished cured you. DAAs are very effective and I think that you're too pessimistic. You will not know the final result however before a test is administered 12 weeks after finishing treatment. In the unlikely event your treatment failed, re-treatment is entirely possible. Dr James Freeman (the doctor in the welcome video on the home page) is a world renowned Hepatitis C expert, and has a lot of experience in treating patients whose treatment had failed, I'm sure he will be able to help. Best of luck to you.
