Hey Cassie,
It's a good idea to post in some of the other communities, as previously explained (how MS typically presents, sx's pattern etc) MS would usually be much lower on the list of possible causes. There are definitely many other conditions that cause similar sx's to those connected to MS, some are neurologically caused but most are not. The undiagnosed symptom community can be a great help because of their wider experiences, if you haven't posted your question there here's the link.....

It definitely wont hurt to getting alternative ideas and with December being months away still, your general doctor could still be involved in looking for potential causes, treating sx's eg medication options, therapy etc. If you find you are escalating and overly anxious, it might be worth considering seeing a psychologist to help develop new coping skills, it can be highly beneficial regardless of what the dx turns out to be, so please don't dismiss it out of hand :o)
FYI, you don't need to repeat a question to get additional input, just type 'bump' in the original and it will come back up on the first page, though it still may not get you anything new if the question already has relevant responses, not in the right community, dissimilar sx's etc etc etc if it does happen trying other communities is always the right way to go.
Cheers..........JJ
