hiya,
I think the MTX success is mixed it helps some more than others, some get remission on it and others get little help others get bad reactions some can last years....
It is now acknowledged that MTX is not much help for the spinal aspects but it was pushed before as they had nothing else. heum,my says it is cheaper we know the side effects and we know how to check for them....
Interestingly MTX is now being used in conjuction with biologicals and there are moved in UK and Aussie to make it compulsory for the subsidised public system.
