Hi and welcome,
Could you please try to make smaller text blocks, just like you did in the beginning of your post, many people with MS have visual and or cognitive issues, that makes reading and comprehending large blocks of text quite difficult and it may effect the number of responses you receive - thanks :o)
Firstly all those tests are common blood tests, positive results point towards various medical conditions that can cause some of what you've mentioned, eg ANA and TSH are from my understanding connected to Lupus, ESR is looking for inflammation, B12 is a very common vitamin deficiency, CBC =complete blood count, CMP =comprehensive metabolic panel, Egfr =estimated glomerular filtration rate (i think the = are liver and kidney function?)
Unilateral Trigeminal Neuralgia (TN) is very commonly caused by dental or anaesthetic related medical procedures, bilateral TN is probably one of the few 'bilateral' symptom that is more suggestive of conditions like MS.
So sorry you've experienced TN it's not called suicide pain for nothing, right, i think i'd rather give birth to a 10 kilo baby than go through that again......TN may be part of the big picture but keep in mind it could also be connected to your prior dental or medical procedures too, unfortunately it's not possible to predict if it is ever going to happen again.
The EMG with nerve conductor study is basically looking for abnormal muscle and or abnormalities in your peripheral nervous system. A lot of people are anxious about these tests, though i think it sounds worse than it usually is, this link explains the process very well.........but if you search the topic in the search box above, you'll find other discussions and experiences that may help to relieve your concerns a bit.
Unilateral visual issues such as Optic Neuritis are very suggestive of conditions like MS but you describe experiencing a 'blind spot' which is a description that's difficult to associate with MS. It could be describing something as minor as a visual floater, migraine related visual etc to something more serious like ON.......?
Bilateral hand tremors is possibly related to your chronic pain, medication side effect etc so possibly another symptom that maybe connected to a more common cause. You also mention your hands actually swelling and the sensation of hands and feet swelling but aren't swollen.....physical swelling isn't primarily a symptom of MS, abnormal sensations definitely are but it's more usual to be an abnormal sensory spot/splodge eg wet spot. I can't recall or locate anything to do with MS in relation to a swelling feeling of entire hands and feet, so not sure about this.....
Your symptoms that are from the waist down, are bilateral and possible symmetrical too (exactly the same both sides), is not usually what happens with MS spinal cord lesions, because MS cord lesions are more commonly too small to cut off the cord and produce bilateral symptoms below the lesion location.
You should definitely see a neurologist, although MS is not at the top of the list of bilateral causation, there are other neurologically related conditions eg structural spinal, Traverse Myelitis etc that need to be looked into....i personally think it's 'more likely' to be something other than MS from my understanding, collection of symptoms, description etc but I think something is definitely going on that needs a neurological consult.
ps I know i haven't gone through everything you've mentioned but hopefully some of it will be a little helpful...
I agree with JJ. You should see a neurologist. The most important part of the MS diagnosis is the clinical exam. A neurologist, preferably an MS specialist, will be able to dectect signs of MS that a PCP cannot.
In addition to the clinical exam you will likely need to have MRI's of your brain, c-spine and t-spine all done with and without a contrast agent.
Neurological issues can be difficult to sort out. Tere is a large amount of symptom overlap. Specfialists are the most effective way to wade through them.
