Medications

I am currently on oxycontin 30 mg 3x per day and 10mg percocet as needed when things get real bad. I also take cymbalta 60 mg once a day and neurontin 800 mg 3x per day. My husband lost his job and we have no insurance so I am looking for a different medication alternative that may benefit me just as well that is not expensive. I really need something that is going to shut down the nerves and assist with the pain and tingling and numbness. Any help will be appreciated. thank you so much all.
