I saw your message was without reply; therefore, I hope I might assist you.
The first thing I would do is to have your heart checked. Women often have different symptoms than men which are all too often overlooked. If your GP sees nothing wrong with your heart or circulatory system, then ask him for a referral to see a neurologist. You should seek the assistance of a neuro who deals with MSers.
Is it MS? I think it is too early. As you are having symptoms, please do see a doctor soon.
