My mobility is severely restricted by a motor neuropathy not related to diabetes. If I take high dose CBD oil my leg muscles, which are prone to cramps, become more relaxed. I have to say, it doesn't improve my mobility - nothing can do that with my condition - but I get no cramps. Like the Neuropathy Cocktail, it is expensive - about £45 a month. That's cheaper than the Cocktail, though, so it might be worth a try. If it can ease mobility neuropathy, there is no reason to suppose it can't improve sensory neuropathies.
If you want give it a try, send me a PM, because there are a few companies that are unreliable about removing the THC (the active ingredient of cannabis that makes you high). CBD oil has no side effects. I use the capsules because CBD oil tastes very bitter.
Do NOT buy these new CBD gummies, they use loads of sugar to mask the taste, and hardly any CBD oil.
