What about hot baths? Heat is often used in massage therapy so a hot/very warm bath might achieve the same relief. I can't tell you what else you can 'take' for your aches and pains, as I'm no doctor, and certainly wouldn't diagnose anyone long distance anyway. But maybe hot baths would help a bit.
You may want to talk to your doctor, or a doctor, as detoxing from pain meds can be dangerous besides just unpleasant. Please be safe when coming off the drugs.
There's also a substance abuse forum here with info in the 'stickies' at the top of the page.
