Welcome, Rog. You have certainly had a rough start. I offer my standard action plan recommendation:
First, take a deep breath. You have found many supportive friends at this site. We come from diverse experiences and hold diverse ideas. We do not agree necessarily in our thoughts on MS; you will probably not agree with some of us either; we only ask for tolerance when we express unconventional ideas.
Second, if you have difficulty finding a neurologist/MS specialist, work with a GP with whom you are most comfortable, who is compassionate and who enjoys being a "disease detective." I have found an interested generalist to be more valuable than many specialists. Begin with a thorough baseline examination including blood tests for your cortisol level, glucose AND insulin levels (these are two DIFFERENT tests), thyroid hormone levels (TSH, Free T4, Free T3, Reserve T3, and antithyroid antibodies), even a liver profile, etc. Ask for a copy of all your test results for your own file.
Third, start your reading with two books: "Multiple Sclerosis: The History of a Disease" by T. Jock Murray, OC, MD and I think "The Multiple Sclerosis Diet Book" by Roy Swank, MD, PhD and Barbara Dugan is a good second book to read or even have. You may be able to get these through your local library.
Fourth, from this day forward, I encourage you to eat a healthy diet (a good idea whether or not you have MS and CERTAINLY with diabetes – type II diabetes, I am sure). Many people find that diet can influence the symptoms of MS. In my opinion, this means a low-carb diet -- removing all sugar (including beer, wine, etc. which have sugar), all artificial sweeteners, including sugar alcohols like sorbitol, xylitol, etc. (These promote insulin production, too.), all trans fats (These also increase insulin.), and white flour, white bread, white potatoes, white rice (in fact, all carbs so far as possible) from your diet. Personally, I think that excess insulin plays a great part in MS. I suspect that Fatty Liver Disease is also involved. Diet is important. You may find the account of Dr. Terry Wahls and her dramatic improvement interesting (http://www.TerryWahls.com
We are glad that you found us; we look forward to your participation and questions. By the way, symptoms very often come and go – I see no reason for the function of your left arm/hand not to come back at some point. Ask your physician about insulin resistance in skeletal muscles as the possible cause.
And if typing becomes a challenge, look into the speech-recognition programs, such as Dragon NaturallySpeaking.
All the best to you.
My hypothesis: excess insulin (hyperinsulinemia) plays a major role in MS, as developed in my initial post: http://www.thisisms.com/forum/general-discussion-f1/topic1878.html "Insulin – Could This Be the Key?"
