All the people with returning tyroid problems who used "Vitamin B6"(or it's other names Pyridoxine, P-5-P, Pyridoxal 5'-phosphate) in a supplement that didn't contain the same amount of vitamin B2(or it's other name Riboflavin)
Highest acceptable ratio of Vitamin B6 to Vitamin B2 isn't more than 6/5 for daily usage.
Most diets provide a higher ratio of these vitamins, that's why I say same.
I don't suggest anyone to use a higher ratio of these vitamins.
I suggest you to use Vitamin B2. Supplements with high vitamin B2 and low vitamin b6 may work also.
For example Bayer's Becozyme-C forte supplies 10 mg of B6 and 15 mg of B2, ratio is 2/3, nearly equal to 0.67, it has significantly more vit b2 than vit b6. It is probably easy to find, for example in a pharmacy, and it will help slowly. Use it once a day until you no longer feel any numbness.
You may experience some numbness, especially while waking from sleep but that's how you're gonna heal. In time, it'll be harder for you to experience numbness in day. For example sitting in a particular position, your legs won't be easily numb as before.
If you have symptoms of overdose/toxicity/negative side effects of included vitamins, stop using and consult a doctor.
Those symptoms are written here http://www.acu-cell.com/bx2.html
If you think already have a symptom of overdose/toxicity/negative side effects of an included vitamin in the supplement you choose, even if it's slight, try to find another one without that vitamin or consult a doctor.
You can increase consumption of water buffalo, sheep or goat milk, or products of them. Use them preferably with whole fat if you have joint problems and not a cholesterol problem that you can't deal with diet.
The fat keeps calcification away.
Excess vit b6 causes spinal nerve damage. You can use some chia or flax seeds or camelina oil, omega 3s will help formation of new nerve cells and increase your good cholesterol.
