Hi all. I’m new to the group. I stumbled into your forum looking for some help and I’ve already seen some encouraging posts. I appreciate it.

About a year and a half ago I began noticing numbness on the bottom of my left foot. I put it aside for several months because I was mainly distracted by a problem with nausea. The nausea was due to my stomach not digesting food as fast as it should (gastro-paresis). I’ve altered my eating habits to manage it. It’s a problem common to diabetes but I don’t have diabetes. In the meantime my numbness spread from my left foot to right foot to hands. At the office my feet feel like my socks are bunching up. I also have tingling and occasional pain. At night now I have feeling of cold or hot in my feet that affects my sleep. I had a brain MRI that was unremarkable. I had a nerve conduction EMG done that concluded there are “subtle electro-diagnostic findings suggestive of mild sensory poly-neuropathy”, and it was noted that this testing does not assess small fiber nerve function. The neurologist said blood test results were normal. He said he didn’t know if the gastro-paresis and PN were related. He didn’t know what caused the PN. He didn’t recommend anything for pain, or any vitamin or supplement regimen to address the PN. He told me to wait awhile and schedule an appointment if it gets worse. I don’t drink or smoke. I don’t take vitamins or drugs. I have a desk job.

I can always go back to the neurologist but I don’t believe he’d have anything new for me if I didn't have anything new to report to him. Here are some results from the labs he ordered: B12 (339 pg/mL) with Folate (22.41 ng/mL), Lyme AB (Neg), TSH (5.08 mIU/liter), ANA SCR (Neg), ESR/WEST (7), RPR (NON REAC), free Thyroxine 1.18 mg/dL, and C REACTIVE PROT (0.2). Just a note last November my TSH and Potassium were elevated for some reason but recently are in normal range.

Should I recommend other tests with the doc as he may have overlooked something? Is there anything I can do on my own, now, any supplements I can take, without knowing the cause that might generally help with PN? Thanks for any advice you can offer.

I'm sure MrsD will be by to talk to you about your B12 results.

The gastroparesis is an autonomic dysfunction and can be the result of PN...all depending on what's causing your PN. I would suggest you inquire about a skin biopsy to check for small fiber neuropathy. It is the definitive test for this (you are correct that EMG cannot assess SFN).

Welcome to NeuroTalk:

Your TSH is considered today to be borderline. Newer ranges end at 3.0, but many doctors still cling to the old range. Hypothyroidism is a cause of PN. That is how mine started 30 yrs ago. I'd get a more aggressive opinion on your thyroid. In my case I had a radioactive uptake scan showing that the gland was damaged. Treatment with only 75mcg of levothyroxine was a huge help. I still have some 10% remaining numbness in 2 toes, but I had a very good response to treatment.
I keep my TSH between 1.5 and 2 now.

The B12 is a bit low and you can raise that up yourself with oral methylcobalamin.
Here is my B12 informational thread:

I would also get tested for Vit D. Low D is showing up now in many people with hard to diagnose conditions and who have chronic pain.

Vit D information:

Do you know what your A1C results are? Hidden insulin resistance and prediabetes, can start the neuropathic process long before frank diabetes. Sometimes fasting morning glucose is normal or even low, when this starts. At that time damage can be happening to your nerves.

You will also want to look at current and past drug use.
Statins for cholesterol cause neuropathy in some people. So do many antibiotics.

Drugs that can cause neuropathy:

You will need to look at your environment for hidden toxins. Arsenic in well water, heavy metals somewhere like lead, mercury or thallium or cadmium, solvent exposure from hobbies or job, (various art or printing activities)
using dry cleaning services may expose you to solvents too.
Pesticides in farming and gardening.
There are many other things as well... including autoimmune problems which need aggressive testing to find the culprit.

Unfortunately, but true, is that many people with PN have to become a detective of sorts, in order to find their trigger, and help improve their lives. Doctors today only do so much and that is not alot.

Thanks for your response and advice and good leads.

En bloc, thanks for information on a possible relationship between PN and Gastro-paresis, and skin biopsy recommendation for small fiber.

Mrs D, thanks for sharing your experience with TSH. I can go back to the neurologist for closer look at that. You asked if an A1C was done. I checked lab reports and don’t see A1C. I do see what appears to be regular no-fasting blood glucose tests that reported 88, 79, and 79 in three labs in the last year (“normal” range 70-110). Also, my cholesterol is normal so no drugs for that.

Before I finished writing this, just now, I decided, based on your comment about the possibility of a toxic anti-biotic, to investigate the antibiotics I have taken. I took Levaquin about the same time the numbness started close to two years ago now. As I recall, my achilles tendons started hurting and I stopped taking the pills. I believe I took 8 of the 10 that were prescribed. Do you believe this could be the cause? I felt no numbness while taking the pills. The tendon pain went away. It’s interesting that the toxin in the Levaquin may have remained in my body after I stopped taking it. Any advice on how I should proceed with the neurologist? I will follow your drug thread. Do you think the Levaquin is the slam dunk cause? Or should I also continue to ask for more aggressive testing for Hypothyroidism, D3, Autoimmune disorder, A1C, and small fiber? In any case, I also believe I’ll start the B12 (methyl-cobaline).

When I was hypothyroid my glucose was always low. Some fastings like 70. When I had my treatment with levothyroxine started my fastings went up to 90. Consistently low blood sugars may indicate a reactive hypoglycemia, which may be starving your nerves when it occurs. When glucose is low, the mitochondria cannot produce energy. A supplement called acetyl carnitine can help encourage fatty acids to be substituted so that the cells can function more normally. Carnitine is normally made in our bodies, but this synthesis may become damaged and fail.

Yes, unfortunately, the Levaquin is a possibility. On that link I gave you, there is a link to Dr. Jay Cohen MD's website where he has suggestions to help overcome fluoroquinolone toxicity.

The mechanism by which these drugs affect tendons is not clearly understood yet. But as far as the nerves go, I suspect a mitochondrial damage of some kind. I have several links in that thread to other places that give more details. Some people believe this damage is permanent, but Dr. Cohen holds out the hope that some supplements may help.

The A1C is an average reading over time that shows spikes in blood sugar that regular testing misses. In many ways it is more useful than glucose readings. Aberrations in blood glucose may be "hidden" for many years, before showing up in standard isolated glucose testing. Some doctors believe these aberrations start the process of diabetic neuropathy.

All of the suggestions that Mrs D has given you, pre-supposes that you have a neurologist who specializes in PN and is one that will intelligently work with you, in testing for causes.
Your past experience with your present neuro
doesn't sound as if s/he is one to do that or has the experience treating various forms of PN.
Possibly a new doc is in the future for you.(?)
