Hi, My son has primary progressive MS and has tried everything out there for MS but without any success. he is bedridden and is so tired, he has a baclofen pump in and because of chronic uti, can't take tysabri anymore. He has a suprapubic catheter and this last time his infection went septic. Is there any other thing that is out there for him to try to get some energy - my neurologist is percribing ritalin, is that good? Do you know of anything else and if you have any trials going on pleaes consider him. Thank you.
