It is possible to have a normal neurological exam with an MS diagnosis - I've been told on recent visits my neuro exams were normal, although the first one, right after my diagnosing event, was probably not quite. I had an abnormal MRI and was diagnosed based on that. I had no other tests. Like you, subsequently have a lot of muscle twitching, which my neuro told me not to worry much about, and some minor tingling and parathesias, particularly in my lower legs, and some vertigo, especially when I first wake up. I had nerve conduction tests done on my arms since I was waking up with numb hands, but the test was normal - I've since figured out that is a circulatory problem due to the way I sleep. So even with MS, not everything is MS.
Although MS is possible, remember it might not be MS. Between now and your next appt., I'd second some of the others' recommendations of getting a good nutritious diet and perhaps even getting with a nutritionist, trying to get some rest, and also trying some relaxing exercise and stress reduction techniques like yoga or whatever might appeal to you. Try to enjoy the upcoming holidays and think about something else. All this is easier said than done, I know, but whatever the origin of your problem is, more stress doesn't help. The doctors' suggestion for a psychological consult might be something to think about. I suspected my diagnosis before I actually had it, and had been referred to a psychologist between recovery from my illness event and actually getting to a neurologist for a consult, which took weeks. The psychologist was there for me when I did get the bad news. If your problems are related to anxiety, a psychologist might help with that. If they do ultimately have some physiological origin like MS (I hope not) or a continuing state of ambiguity (I hope not) the psychologist can still be of help by giving you someone away from friends and family to help deal with the stress.
Good luck, and may your symptoms just go away!
