Welcome to ThisIsMS, Abdul. You have an unfortunate situation; obviously, you cannot rely on your wife's family for information; you must educate yourself on MS. I urge you to visit a library or bookstore and find all the books on MS that you can and begin reading, reading, reading. The "Reading Nook" forum on this website can suggest many titles – my personal favorite is
Multiple Sclerosis: The History of a Disease by T Jock Murray (It was written in English; I do not know if it has been translated into your first language.)
On this website you will find many opinions on the cause and best treatment for this disease. This disease is still a mystery; there is no absolutely right answer yet! We members of ThisIs MS share our ideas and try to encourage each other. We come from many different countries and cultures; you will have to choose those ideas that fit for your situation; my suggestions may not be comfortable for you and your wife.
If it is possible for you in Egypt, I encourage you to accept your wife's difficulty as yours too – the two of you are a team working together against MS. I hope you can find sympathetic medical doctors to add to your team. I think the answers to MS will be found soon.
In the meantime, many people have found a no-carb diet and exercise to be helpful. The story of Dr. Terry Wahls (
http://www.TerryWahls.org) is especially dramatic.
We are happy that you found this website; we welcome your questions – we may not always have the answers. The future for you, your wife, and son may seem bleak at times, but I feel there is reason for optimism – the future will improve for all of us.
