I have a incomplete spinal injury since 6/7/08. I am now walking with a 4 prong cane but still have alot of problem with balance. I get tingling feelings in both arms and legs. I now take, Allopurinal, Digoxin, Vesicare,baclofen, multi vitamin, cranberry pills, vitamin c and citrucel. Does Ampyra have any bad interactions with any of these pills?
