Hi, Everyone!

I've had tingling that started in the front of my left shin for about a year now (since October 2018). It spread up to my knee and front of my thigh.

I had a brain MRI (clear) a lumbar MRI (clear) and a lumbarsac x-ray (clear). I've had multiple blood tests, only raised ESR (36mm at the highest) and CRP (1.5 mg/dl), but rheumatologist and neurologist both said those could be due to obesity, not anything concerning. ANA markers are negative. No diabetes. No MS.

My left elbow and left side of my face also tingles. My tongue burns at times.

Within the past 5 weeks, my foot began to hurt and got numb below the ankle. Orthopedist says it's Sural Neuritis.

My neurologist asked "is this something you can live with? then you graduated from me."

I don't feel like that's helpful.

I'm not sure where to go with this - I feel like something is wrong, and why are they not testing? My neuro didn't even do any nerve conduction? What on earth?

I'm terrified I have something like amyloidosis because nothing else is showing up... do I keep pressing?? I have toenail fungus (and have for 5 years now) but I read that could be due to amyloid deposits. I'm so scared. I don't really know what to do here. My doctors have all put this up to anxiety and just "idiopathic" neuropathy without thorough diagnostic testing.

Has this happened to anyone else? I don't know what to push for? Nerve conduction? Biopsy? Do I worry about amyloid or is that a longshot?

Looking back over my testing from 2019, I see the following:

CBC w/diff: nothing stands out
CMP: nothing stands out
ESR: 36 mm/hr
CRP: 1.5 mg/dl
Lyme: negative
ANA: negative

MRI lumbar: clear

MRI brain: A few foci of subcortical, periventricular, and deep white matter T2 FLAIR hyperintensity which are stable and nonspecific but can be associated with demyelinating disease in the appropriate clinical setting.
There is a subtle T2 FLAIR hyperintensity in the left posterior frontal cortex, image 4 series #4 which is of uncertain significance.

3 years ago I presented to my GP with vertigo / heat intolerance / overall feeling of illness. I was sent to a neurologist who ordered an MRI and said it might be MS. My MRI from 3 years ago looks the same as my MRI now (with lesions), so new neurologist said it is *not* MS.

A rheumatologist ordered (2016):

PROTEIN ELECTROPHERISIS which included:

Serum Protein Electrophoresis: An increase in acute phase reactants, suggestive of an inflammatory process.

Serum Immunofixation: Polyclonal immunoglobulins. Negative for monoclonal paraproteins.

My question is - since these were ordered 3 years ago, would it be beneficial to have my rheumatologist test again? My tingling/numbness began over a year ago, so it would have been 2 years between testing and new onset of symptoms.

Or, should I continue to press my neuro for a more extensive workup?

Thank you, these links are perfect.

I'm actually scheduled with the rheumatologist again this week. While I can't imagine the immunofixation would have changed within 3 years, I'm going to have them re-test that along with some other bloodwork from this chart, if they are able.

My neurologist still hasn't called back after leaving several messages. Probably time for a new neurologist...

I'd also forgot to mention - my B12 is on the low end of normal - it reads at 303 when the range for the lab is 180-914. Could the 303 be the cause of tingling, nerve pain, and even a numb spot? (tinel's sign positive on sural nerve, btw, not sure if that matters?)

yes....you need to raise that b 12 level. in other countries 303 would be considered to be low and problematic. take at least 1000 mcg of methylcobalamin b12 a day. if you do a search of b12 on this site, there is a wealth of information.

Thank you! I have sublingual tablets that I will start taking. 5 years ago when vertigo presented by b12 was around 200-300. I was getting b12 shots for about a year but my neuro retired and I stopped. Most recent reading from 12/2018 was 303. I’m sure it’s been teetering on that for 4 years. At least. I appreciate the boards and the advice!

Just an update:

Went to a rheumatologist, monoclonal disease was ruled out (thank goodness, was worried about myeloma as my uncle died of it, and amyloidosis because I'm a hypochondriac and saw it on the internet). ANA is negative. Rheum factors are negative. SED rate dropped from 36 to 11 (hooray!) but CRP remains elevated at 1.1 (rheum said that is not of much concern).

B12 levels have improved - from 200 to 500. I still have some issues.

Orthopedist ordered nerve conduction and EMG, which I just had done Monday. They are both normal.

My left sural nerve area (heel/bottom of foot) is still numb to the touch and VERY painful when I flex my foot with my leg out (ie: walk lol), tingling all over my left leg (shin, thigh, both on the front and back), The left side of my face tingles, and my left fingertips are starting to feel tingling / odd as well.

I'm seeing a new neurologist as mine said "go to the ER" then said "well if you don't want to do that just wait and see" without seeing me, only hearing my worsening numbness over the phone. So that's cool. New neuro is in April. (to be noted, I do have lesions on my brain, my first retired neuro said he suspected MS but retired before I had a 2nd "flare up," the new one said "this is a healthy brain" and dismissed me immediately).

I'm not sure where to go with this, I have no idea what could be causing it? I don't want to google due to my hypochondria, but the constant numbness in my heel / sural nerve is concerning to me, as well as the new onset tingling in my left toes and left fingertips. I feel like I'm going crazy - I started seeing a therapist for my health anxiety / generalized anxiety but I know this isn't all in my head, especially since I have actual tearing pain / numbness now instead of "burning / tingling" (which seems to make people not believe you).

I feel so exhausted (and broke!) by this process... sigh.

OP: I have the tingling down my right shin mostly and this is side of body I had hip replacement.
For me, Topricin homeopathic lotion is my best friend for all this...I can't imagine not having my supply -- the comfort this Topricin brings me.

And my B12 levels have always come in high as I've been taking Methyl B12 for years.

There is so much good info here for the PN issues and I am one who does not count on doc's drugs for help. I use all supplements and am much much better off... The longer one lives, the more they learn.

Hi, everyone!

I wanted to update, as I've been sent to a neurologist who actually seems to be putting in some effort. My pain in my feet has gotten worse, and my tingling/numbness has remained constant. This has been ongoing since October 2018.

No diabetes, B12 has been low in the past but it's climbing (currently sitting at 500), no thyroid issues - I do have PCOS just diagnosed, but other than that, no real oddities in my bloodwork (aside from elevated inflammatory markers that no one has been able to pinpoint).

My neurologist is looking over ALL of my MRIs and the reports. If she suspects CNS (she does not currently), she will order a lumbar puncture.

If she does not suspect CNS based on the MRIs, she is ordering her own EMG/NCS as she is not thrilled with the one the ortho ordered (it is incomplete).

If that shows nothing, she will be ordering a skin punch to look for small fiber involvement.

Her initial impression:

"My strongest suspicion is for a peripheral process, either multiple focal compressive/traumatic lesions, versus radiculopathy, versus more diffuse small fiber neuropathy that may have an underlying autoimmune/inflammatory etiology."

Because my SED rate has remained elevated (except for one lower reading) and my CRP as well, she's leaning more toward autoimmune/inflammatory with peripheral involvement than anything else.

That being said - I've had a full range of Rheum/autoimmune testing.

I think the most important to note for me, would be:

GAMMA PERCENT

I had an immunofixation done in 2016 as well, with no monoclonal proteins identified. I asked the Rheum to repeat and she said that was unnecessary, since it would have shown in 2016, but she repeated the SPEP for my peace of mind.

I guess I'm feeling more comfortable with this neurologist (out of University of Rochester in Rochester, NY) than my last (who completely dismissed me) but when I mentioned perhaps something like Amyloid, she said it can be a consideration because "it can do some weird stuff," though she said it's reassuring I did not have a monoclonal protein.

I've been hyper-focused on amyloid due to my health anxiety, and I'm wondering if my doctor is just being thorough not to rule it out because she knows I've been dismissed in the past, or if it really is something to consider?

Aside from that, I'm at a loss as to what this could be, eating away at my nerves and setting me on fire...

(also to note, I'm 37 years old, female, so neuropathy in general is a bit odd to set in at this age, I'm told)
