I see a neurologist regularly (twice a year) due to some ulnar neuropathy in my right arm and a Vitamin B12 deficiency. I also take Enbrel. When my arm symptoms initially started (numbness and weakness, no tingling), my rheumatologist sent me to a neurologist to rule out an Enbrel-induced demyelinating disease such as MS. The neurologist did a brain scan as a precaution (it was normal) but told me that my symptoms -- present in just one arm -- were not how such diseases initially present. She said that when they see a biologic-induced demyelinating syndrome it is typically bilateral and begins in the feet and lower legs. Hope that helps.
Have you gotten your B12 results because a B12 deficiency can cause all sorts of weird neurological symptoms?
The GP was kinda useless like a lot of GP's are... She ordered a complete blood count (CBC) and told me we'll only do the B12 test if there's something wrong in the CBC... Told me the ususal symptom of B12 deficiency are more along the line of numbness like when you go to the dentist. She won't even send me for an MRI since I passed the neurological exam but it was kind of half-assed... She did ask for thyroid, diabetes, liver function, etc. so we'll see what the blood results tell me. As far as feeling mini-tingles here and there she says it's not how MS presents. Says the tingles are usually constant or at least last a few hours and affect a whole foot, leg or even en entire side of body. That intermittent tingles lasting for half a second that appear anywhere are not typical of MS.
Today my dizziness is better, about 70% gone but my right arm feels weak. It's not numb per se because it hurts when I pinch it but it "feels" numb if that makes sense? No tingles I just feel like it's weaker, like it hangs more than my left arm. I feel like it trembles easier than the other arm if I keep it raised.
I know it's not REALLY weak though because I can do push-ups and I can even stand on one arm in push-up position which I guess I couldn't do if it was weak or numb from a neuro problem. It's kind of driving me crazy. I can still type super fast like I'm used to but I feel clumsier when I pick up objects even though I don't drop them or anything. It's like a feeling inside that I feel like I could drop stuff but I don't. I think it's getting to the point where I'm just super conscious of every movement instead of doing them naturally if that makes sense.
My problem is that it's all based on "feeling". There's no objective loss of strength or function (yet?) that they can pinpoint with a physical exam. GP flat out told me she won't send me for an MRI cause it might pick up something unrelated and benign that they'd have to investigate and it would cause more useless anxiety. She's convinced I suffer from depression, anxiety and exhaustion, that thinking about symptoms all the time makes them appear in a somatic fashion.
So yeah I guess I'm crazy. Waiting for something to happen like falling down on the street or losing control of a limb so that I'll be taken seriously. I mean I WISH it's only psychological but it's hard to convince yourself of that when you have strange symptoms.
