Other than a little soreness in both arms
the next day, I didn't particularly feel bad at all. I suffer from chronic back pain
however, and it pretty much rules the day as far as what the brain can perceive.... Kind of like a bad accident, if you break your leg, you might not notice the deep gash your arm. :-)
First shot for HCV was 3 hours ago, and so far, still just the backache. lol Take care, and good luck!
