The MRI is telling your doctor that there are two areas of your brain -- "foci", commonly called lesions -- that are indicative of a demylinating disease like MS, or a circulatory problem -- mini strokes -- that the doctor needs to look at, and then, based on what else he finds in his exam and testing of you, will lead him to a diagnosis.
You could have MS, or you could have something more commonly called TIA's, small strokes, going on. That's the "microangiopathic gliosis" thing, and you can read more about that here: http://stroke.ahajournals.org/cgi/content/full/30/8/1637
The FLAIR is a kind of MRI done to specifically exam the brain for both these conditions. It's the name of that test.
So the neuro will look at that MRI -- presumably the chiropractor sent a copy to the neuro, too..and if not, you should make sure that happens before your appointment.
Then the neuro will exam you thoroughly, asking for past medical history (if you've seen a doctor for similar problems before, you should make sure those records get to your neuro before your visit, if at all possible). You'll be tested for all sorts of other disorders that might be causing your symptoms -- lots of blood tests, for example, to rule out MS (there is no blood test that can confirm MS), possibly tests called "evoked potential" testing, where the brain waves from your brain to your eyes will be measured, strength and balance testing, all sorts of things,
to try to find out what is causing your symptoms, and what to do about them.
If you do have MS -- and it's too early to tell, and of course I can't diagnose you, nor can anyone else here -- you first need to know that it does not mean that you can't run the soccer fields, necessarily, or that you'll become severely disabled. Many people with MS live normal usual lives with only minor difficulties and adjustments. But you certainly are of the "right" age -- MS generally strikes between the ages of 20 and 45 or so.
As for the medicines "working" -- it depends on what you mean by "working". They will not cure MS. They will only slow down the progression of the disease, meaning you may have fewer exacerbations (or flares or attacks - all the same thing, just different words to describe them). Fewer exacerbations brings the promise of less disability, as the disease progresses.
MS is not a terminal illness. Folks live a long time with it. I was diagnosed when I was a few years younger than you. I'm now 60, and still here...still with MS, but still alive, living with my husband in our home, cooking, cleaning, shopping, living a relatively normal life...just with MS. Many folks here much younger than I also have MS, also are living their lives, even plotting to enlarge their families.
For now -- you need to do these things, in preparation for your neuro visit:
Make sure he has a copy of that MRI
Get all your other medical records and make sure he has copies of those
List your symptoms that caused you to start exploring this problem. List them from the most troublesome to the least troublesome, and if you can, try to note when they first occured, and how long they lasted (or if they're still continuing).
Take someone with you to the doctor's visit. He'll likely ask you a ton of questions, and tell you all sorts of things you'll need to do (schedule other tests, etc.) and it's very easy to get confused and intimidated and forget to ask about things. If you have someone with you who is familiar with your list of symptoms and possible questions, they can help keep all of it sorted, and maybe even take notes so you won't lose important information.
Let me know if I can answer anything else...just remember I'm NOT a doctor, nor medical professional, nor do I pretend to be one here. Anything I've said in this post is my opinion, and my opinion only.
Good luck with your neuro appointment.
