Hi. Welcome to the MedHelp MS forum. I am sorry to hear that you are having such a difficult time. Stick with us here and many folks will help you get through this difficult time. More members will chime in before Tuesday to offer their guidance as well.
It is good that you will be having a brain MRI on Tuesday. Are your familiar with the contrast agent used for MRI's? If the docs are looking for the possibility of MS, a contrast agent should ABSOLUTELY be used. Here's a link to read:

It is not uncommon to discover MS-type lesions by chance, often after an accident of some type. It is entirely possible that you do not have MS and your problems with walking could be caused from the ruptured discs. The other symptoms you are having could be caused by something less serious than MS. Once you have your brain MRI, your neurologist should have a clearer idea of what is going on with you.
I am concerned that whatever the cause of your problems are that they have gone unaddressed for so many months. How often do you see your neurologist? He should be watching you very closely. Did he see the suspicious x-ray OR did anyone think to order an MRI of that area? Those suspicious are should be MRI'ed as well.
Having an MRI for the first time can be intimidating. I usually take a calming medication because I am mildly claustrophobic. You will the noises of the magnets as they change positions and also change in tone and rhythm. Sometimes the noise is muffled and then increases in volume. It does not hurt. The only type of pain you may experience is from the needle stick when the dye is injected into a vein. A series of pictures will be taken, first without the dye, and then more after it is injected.
This is the criteria used when diagnosing MS:
