Allergic to morphine, vicodin, codeine, nsaids. chronically ill, looking for pain relief. tylenol (acetaminophen) is useless. tramadol ok? other suggestions?

Yes: Tramadol would be a good choice.

Painful situation: You have a difficult problem which is not uncommon. You need a concerned physician to review the reactions and what alternatives are available for treatment. Ideally you could see an allergist and a pain specialist to resolve this issue. Also i would be looking into alternative methods of controlling pain such as stress reduction meditation and even possibly acupuncture.
