Celticgal – My suggestions will sound familiar to old friends here:
Find a GP or internist, who is sympathetic and compassionate and willing to work with you in a partnership.
Request a baseline assessment, a thorough physical exam and a thorough workup of blood tests, including cortisol levels, insulin (which is different from glucose), all thyroid hormones, vitamin D levels, etc.
Start your own file at home with copies of every test result you get.
Read, read, read. Go into each doctor's appointment with a page of written questions that have come to you as you read and educate yourself on MS.
Your description of your condition COULD be MS; there are also MANY other possible reasons for your symptoms. You need a doctor who is also a good detective – there are many explanations to be ruled out first.
