Hello: I've had a gathering in my right hand for 10 years, that recently has become very painful and fingers seem to lock. I've since developed a knob in the other hand.With some pain,but nothing like the right hand. I can't squeeze a teapot handle or open a door for the pain. Father and sister has/had similar difficulties. Where do you buy DMSO in Canada. Any other suggestion???? Or the US for that matter. An operation may not be civered finacially here at the moment. Sincerely Gemme8
