Here's my situation: In late 2007, I went to the doctor for general muscle and body pain. No one was able to find anything. After all kinds of tests, scans, etc., the docs found -- by accident, sounds like -- HCV, genotype 2, about a year later. I recently completed 24 weeks of interferon and ribavirin (mid-May), and now, the muscle and body pain have returned and seem to be intensifying. My question is: It is possible that I had/have undiagnosed multiple sclerosis, and then when I started treatment the interferon kept the MS from progressing?
