I've suffered Osteo-Arthritis in most joints , had a hip replaced and spinal surgery, I have tried all of the things mentioned above at some time in the last 20yrs and found none of them help at all. You have to give them a good 4/6 mth trial though as different things help different people , my OH swears by his copper wrist band but I found them useless, likewise Glucosamine and Rose Hip and all the other things that have been recommended. I find taking the Anti-inflammatory Meds my GP gives me , regular swimming/walking and knitting keep the pain and swelling at a tolerable level. I occasionally take Ibuprofen on a bad day but if you have Osteo-Arthritis the pain is at its worst while the changes are taking place in the joint then the pain can subside but you are left with less range of movement and changes to the bone in the joints hence the nodes on fingers and in my case toes as well.. its certainly a very debilitating desease but you have to keep moving , I do things in half hour stints , work for half an hour then a short rest and that way although it takes me longer I find I can keep going.. my joints seize up if I don't move them often.. I rarely sit still for more than half an hour .
If you are suffering do see your GP and see if Anti-inflammatories are suitable for you they do help I couldn't manage without them.
sorry I didn't mean to write a book..lol
