Should I take Vicodin for my shingles/impetigo pain?

About a month ago I got shingles under my arm and the pain was HORRIBLE. They went away and about a week ago I thought I got them again and I just went to my doctor today and said that they aren't shingles but they might be impetigo. And they do hurt a lot but not as bad as the shingles did before. My doctor prescribed me Vicodin for the pain and I've been debating wether or not I should take them because they are very strong pain pills and I'm worry about addiction and withdrawls after taking them. I took Vicodin back in November and early December of 2010 after an oral surgery to remove my wisdom teeth. It worked great and I didn't have any withdrawls after taking them or addiction to them. I come from a family with very addicting genes in our blood line and my older brother got addicted to pain pills but he was taking them for no reason but to get high and feel good. In my case, it's to cure actual pain. My dad is against narcotics/drugs and he just had a heart attack and a surgery to remove his gaul bladder and his doctor prescribed him pain pills to recover. He refused to take them, yet he is an alcoholic and he decided to use alcohol to cure his pain and that didn't go well at all cause he fell down the stairs and basically cracked his head open from being drunk and dillusional. But anyway, I would like some opinions on my situation on wether or not I should take my Vicodin or not. The pain isn't to horrible and I can deal with it just hurts a lot when I lift my left arm. My doctor also prescribed me some oral anti-biotics which I don't have a problem with at all because those are needed. But yea, would it be smart for me to take my Vicodin? I live in Florida and Florida has the biggest drug and pill pushing doctors and that's been a very big problem lately here in Florida. But anyway I guess my case isn't such a big deal but I want to be safe and just make sure it's necesary for me to take my pain medication. Should I do it? Or should I not? Thanks! :)
