"i take extra strength voltaren gel 2.32% for ra pain. i purchase it otc in canada. it really is about the only thing that touches the pain. my wife however cannot stand the smell of it when i use it. she says it makes her short of breath. i have been using voltaren for years and just this last june she complained loudly. i haven&#039;t used it since. hence i can&#039;t sleep because of the pain. i do not smell much of anything besides the alcohol when it is drying."
