I did not know they did baclofen injections into the spine more than once, and that is to see you are a good candidate for the baclofen pump. I took what my neuro saidwas the maximum dose of baclofen (60 mgs) for a couple of years, and it did not help at all. I tried zanaflex at a low dose and it seemed to be helping a bit, but it made me too nauseated. I have always been too leery of trying the pump too.
