Hi, Fastaire, and welcome to the forum. Interesting case. I am hoping and praying that you had acute hepatitis that your own immune system kicked out. This happened to me with hep B, but no so lucky with hep C. I also did IV drugs when I was young and curious. If this is the case, you would have the antibody for hep C or B. Back in '71, hep C was known as non-A, non-B. It could be that it has lain dormant all these years and that something triggered another acute episode.
First of all, the biopsy is a good idea. You will know for sure how much damage has been done to your liver. You should be sure that it's done with imagining (portable ultrasound), so that the radiologist can see exactly where they are going.
If it is discovered that the hep C is acute (continuing to damage your liver), then you certainly should consider treatment. There are new ones on the horizon that are all oral and contain no interferon.
Meanwhile, check out the folder at the top of the page entitled Hepatitis Resources for lots of good info.
