Hallo Uwe,
the best remedy for arthritis is bee venom or the sting of bees. I use it in my own practrice with tremendous sucess!!!
And its not true that there is no possibility in Canada
just look :
http://apitherapy.com/canada.php
or contact Michail Simics under
www.beevenom.com
He is producing beevenom and for sure can give you an advice where you can find a therapist who does it.
Some dietary corrections are for sure recommended. Such as avoiding porcs meat and other acidic producing food.
This should be evaluated in an individual prescription.
Good luck from senioraladin from the german ground crew
