Okay, so firstly, I don't really know how good of an idea using herbal remedies really is. Maybe I'm biased, my doctor says if I want a herbal remedy to go and eat ditch grass and save myself money (he's kind of abrasive sometimes), so obviously that's my perspective. From a more objective approach, most medications, though very technical and not exactly appearing herbal, are just the refined materials that we're getting from herbal remedies. For example Aspirin is made from salicylic acid, which is found in Willow tree back and leaves, which is actually a remedy on this list.
That said, since I don't see how it can hurt,
I went and found some herbal remedies for chronic pain on Web MD with a search, some that were recommended were: turmeric, green tea, ginger, rosemary, cat's claw, devil's claw, and willow bark to prevent inflammation.
The page specifically said that
turmeric was regarded highly among patients with arthritis.
Capsaicin good for pain relief by rubbing on skin (don't apply to sensitive areas, wash hands, note that irritation will occur for a brief time initially).
Glucosamine sulfate was good for joint pain.
SAMe was good for osteoarthritis patients.
Acetyl-L-carnitine was good for correcting nerve pain, specifically with diabetics.
Fish oil (for vitamin 3) and sufficient vitamin D (linked to lower levels of pain in studies) were good with pain relief....
In addition to trying natural cures, some people will also see a naturopath, many communities have them (mine does). While their methods are disputed, they're definitely safe, and can give you some ideas on where to start with natural medicine. They also tend to promote a healthy lifestyle, which is actually always a plus. Just be careful when dealing with advanced illnesses, as some infamous naturopaths will try to use their remedies to treat things like cancer, when you really would probably be better off with something like radiation treatment, however upsetting that would be.
That's all I could find...
