Suggest Medicines For Chronic Pain Other Than Oxycodone

Hello I was hoping you could answer my question? I have been using oxycodone and oxycontin for almost a year and a half and the med is not working as well for me? Are there any suggestions you could offer for something that would work as well? My Dr wants to put me on Exalgo and Dilaudid to reset my pain receptiors. Which is fine but I am afraid It won't be strong enough? Do you have any other's that might work better?
