Wow, T, it sounds like your doctor is very much on top of things.  You were able to undergo the nerve conduction testing during this intial visit?  Wow.   Very clever to look up the diagnosis codes (very smart, I do the same thing).  The codes indicate what the evidence or concern is right now.  I guess your physical exam pointed towards the intention tremor, while the EMG pointed towards some type of peripheral neuropathy (which can have many different causes).  These are not really diseases in and of themselves, but symptoms.   It's very nice that the doctor wants to see you back in two weeks.  The blood tests should be back by then and perhaps a more formal reading of the tests you underwent today will have been conducted.  He is taking it one step at a time.   (BTW, I would not hesitate to say, "I'm concerned that this 'could' be MS. What is your opinion at this time?")
