has anyone with this wretched condition been told it could be because of overdosing on thyroxine?
peripheral neuropathy: has anyone with this... - Thyroid UK
peripheral neuropathy
More like under-dosing! But, can also be caused by low B12.
What were your latest results to make them say you are overdosing (You probably aren't!)?
Low B12 and even folate can cause nerve symptoms.
When hypothyroid and on levothyroxine low vitamin D, folate, ferritin or B12 are extremely common
It’s also much more common to have low vitamin levels as we get older
What vitamin supplements are you currently taking
How much levothyroxine are you currently taking
Do you always get same brand levothyroxine at each prescription
Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis
In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)
Recommended on here that all thyroid blood tests early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

Ive been hypothyroid for 30 years. Recently developed peripheral neuropathy and vit b12 deficiency is probably the cause. Now on b12 injections and neuropaethy a little improved. Still there but the intense burning in toes has gone.
Thank you
Are you in Uk?
What kind of B12 test did you do?
My dr says levels OK
what are your most recent vitamin results
Folate, B12, ferritin and vitamin D ?
optimal vitamin levels are
Vitamin D at least over 80nmol
Serum B12 at least over 500
Active B12 at least over 70
Folate and ferritin at least half way through range
B12 range in U.K. is too wide
Interesting that in this research B12 below 400 is considered inadequate
healthunlocked.com/thyroidu...
serum Vit B12 589ng/L (130.0-800.0)no other, folate 8.1, (4.0-27)ferritin102 (13.0-150). No D thank you
folate is low especially if you’re supplementing
What vitamin supplements are you currently taking
You could test vitamin D on its own
Test twice yearly via NHS private testing service when supplementing
so appreciate your concern
Am not taking folate thought I was.
Have been taking B12 1000ug, Magnesium 375mg,zinc 15mg
Recently for the peripheral neuropathy, an American formula Nerve Renew per day RALA 600 mg, D 50mg, B2 16 mg, B6 16 mg, B12( asmethylcobalamin), Benfotiamine 12 mg,
Plus 112 thyroxin
Am prediabetic
How often do you have a B12 injection ? Arr you supplementing folate too ?
Following my 6 loading doses im on 12 weekly injections. I take 800 ug folic acid ( self prescibed ) as it was in range but low.
How is your D deficiency being treated ? Also neurological issues should be treated more than 3-monthly.
I don’t have injections. Am supplementing folate
Perhaps consider Vitamin B1 in the form of benfotamine for peripheral neuropathy and check levels of vitamin D which influences insulin resistance. Vitamin B1 gets used up by high blood sugar.
Both my feet are pretty numb, peripheral neuropathy diagnosed years ago. Absolutely nothing done. When I mention it to the GP, he/she ignores me.
I can walk on lego without screaming!
