I don't know if you're open to this, but Ayurveda seems to think it can do more than what is normal for multiple sclerosis. Apparently there is even some research going on in India about this right now. You can look up "Multiple Sclerosis is not an Autoimmune Disorder, according to Ayurveda" by Dr. Prasanth Raghavan. They might be able to at least make Sean's multiple sclerosis symptoms better. Another thing you could try is traditional chinese medicine, which includes acupuncture and herbal formulas. I know acupuncture is supposed to affect the nerves in the body, so this also might be able to help in some way. I wouldn't really know, but it might be worth investigating. I would definitely check out both Ayurveda and traditional chinese medicine because what have you got to lose? Sean can still keep taking all his drugs; these would just be options on the side that might help him get better.
lspence, I am praying for Sean
lspence, I am praying for you
