Hi, and Welcome to the forum! You have had far more than your share of the crummy stuff happening to your body.
For many years it was thought that Type I Diabetes and MS were mutually exclusive due to the kind of tissue type which was associated with each disease. However, that was disproven and discovered that there was an association between the two. If you wish I can probably dredge up the study and cite.
I am not aware of any association between Crohns and MS.
But, you said something that piqued my interest. In people with MS the use of a anti-TNF med (Tumor Necrosing Factor Blocker), such as Remicade, is known to dramatically worsen MS. There is also some evidence that these drugs may bring on or precipitate the beging of MS. So, in people with both MS and diseases like Crohn's, RA, Psoriasis, etc the use of an TNF blocker is highly discouraged. If the MS has not yet surfaced, then no one would know of the contraindication.
While no one can diagnose anything online, I would like to look at some of what you have told us in the context of MS. I agree that the repeated pain in your sternum does sound a little like the tightness that is associated with the MS HUG. You can look this up online and read all about it. It also could be the severe esophageal spasm that can be associated with esophageal reflux - I don't know if that is associated with Crohns or not. It sounds like the onset of your problems was in your mid-30's - pretty classic for MS.
However, the tightness in your sternum seems to preceed ther onset of other symptoms all of which sound VERY neurological and many of which are common in MS. You seem to have "waves" of symptoms that occur and then resolve leaving you to feel better. This is a pretty classic pattern for the most common form of MS, called Relapsing Remitting. Here is an article on the different types of MS:

and here is another on the definitions of what makes up an attack (relapse, exacerbation, flare) of MS:

Did the visual problems occur all the time or in attacks also where some or all of your vision returned? I suspect that the ophthalmologist was also looking in your dilated
eyes for signs of optic neuritis. Many of your symptoms are classic for that and it is one of the most common problems in MS. However, many ophtho's also are ignorant of the fact that there is no sign of optic neuritis on physical exam in 64% of people with MS and optic neuritis. This is because the lesions are too far back on the otpic nerve to show the signs in the eye itself.
The pain on one side of your face, often felt as dental pain, is pretty classic for MS also. It is something called Trigeminal Neuralgia, meaning a false pain in the nerve (the Trigeminal Nerve) that brings snesation from the face, gums, lips and tongue to the brain. Usually older people (older than 60 or so) get Trigeminal Neuralgia. When it is seen in a young person it should trigger the thought of MS and an MRI.
The dizziness is another of the most common symptoms in MS. So in people with severe dizziness and with falling an MRI should be done to check for lesions in the brainstem and in the part of the brain responsible for coordination, called the cerebellum.
So, here is one way to look at what has been happening to your for the last 9 years or so. You had some severe symptoms referable to your abdomen and were diagnosed with Crohns Disease. I gather the diagnosis of Crohn's was made by biopsy? You were treated with Remicade (an TNF blocker) and steroids and for a while felt much better, but then severe fatigue set in (a classic symptom in MS). I can provide you with studies on this if you like.
Then over the next four years you had symptoms suggestive (to me) of optic neuritis, by exam and the first VER were negative. Doesn't mean a lot, though the VER is a very good test. But no MRI yet???? But, you began having pain in your left hip and leg which was not diagnosed, but a massage therapist thought that it felt like spasticity. Man, this should have triggered a visit to the neurologist, because localized spasticity screams "spinal cord lesion" like you would see in MS. Do you know if your reflexes were/are hyperactive in your left leg? Then, 3 months of severe pain resolve within a week. That is how MS relapses often resolve and is one of the reasons the docs often think we are looney tunes.
Last winter was horrible and you had more attacks of sternum pain, falling, facial pain, and vision loss. Does/has you vision ever improved in between bouts?
Now the doc is really thinking MS and an MRI shows multiple lesions. !!!!????? At this point if there has been a careful ruleout of those other diseases that mimic MS and cause brain and spine lesions, you probably qualify right now for a diagnosis of Definite MS.
Now, that is just one way of interpreting what you have told us as though we were trying to explain what you have gone through with a diagnosis of MS. It is not the only way. So, my answer to you about whether MS is likely enough to go through more testing is YES!!!
Let me give you an explanation in a nutshell of the process in which MS is diagnosed.
First a neurologist would examine the history of what you have gone through to see if there is any pattern of problems that are typically seen in MS. The answer here is a strong "YES". The eye, the falling, the pain/stiffness in one leg, the facial pain, etc. Then they look for a pattern of relapses, where some symptoms come on, stay for at least 24 hours and then resolve partially or completely. You clearly have had multiple attacks of all of this.
The second thing the neuro looks for is abnormalities on the neuro exam. You didn't give us much info about this, but it would be things like your loss of fields of vision, changes in pupil response, hyperactive reflexes, spasticity, falling when you stand with your eyes closed, areas of skin with decreased sensation, weakness, etc. There are many dozens of tests they do.
Then typically the neuro orders an MRI. If the MRI has lesions on it the evidence is strong for MS IF the patient does have a history of two or more attacks and has evidence of damage on the neuro exam in two or more areas of the nervous system.
There is only one mandatory thing left. The neuro needs to rule out all better explanations for the problems and the MRI lesions. These are things like RA, Lupus, Lyme, Syphillis, AIDS, Sarcoidosis, other autoimmune diseases. These are tested for by blood tests. MS is a diagnosis of "exclusion". Better reasons must be ruled out.
