Hello plezhelp - welcome to the forum. If you are in legitimate pain, then you are not addicted, but dependent on the pain medication, just like a diabetic is dependent on insulin for their condition. Almost all pain blocking medications are opiate based and thus addicting. I don't know if suboxone will relieve pain, since I have never tried it.
Having legitimate pain and taking the pain medication as prescribed does not make you an addict. I am currently taking Percocets for my reoccurring pain and there are others in the forum that are the same. There's a new drug on the market called Nucynta that is suppose to have less addicting and withdrawals effects than other opiate-based products, but it still is opiate based and therefore, I believe, will have the same effects. I took Nucynta for a while, and you can real my post here if you would like my personal opinion.
For pain, there are few substitutes than opiate-based drugs, but there are alternatives like Tramadol or other lower dose drugs that you might want to talk about with your pain mgt doc. Talk to them and your pharmacist for additional information. They may be familiar with other drugs that will relieve pain. My pharmacist takes the time to talk about different drugs and their uses.
Sometimes long term use of opiate based drugs are a reality that we have to consider. I'll have pain for the rest of my life, or until I decide on surgery, so I take the Percs as needed for pain. You may want to consider tapering back until you take just enough to stop the pain or are at a pain level that you can tolerate. I don't shoot for no pain, but for reduced pain that I can tolerate. Hope that helps.
