Numbness and Tingling in the Hands and Feet: Causes, Red Flags and Tests
Numbness and tingling in the feet or hands often come from peripheral neuropathy. Diabetes is the leading cause, and low vitamin B12, alcohol and toxins are others (NINDS - Peripheral neuropathy). Simple blood tests can find several of these. Treating the cause can sometimes let nerves recover, which a supplement such as Neuro Recall cannot do on its own.

What is peripheral neuropathy?
Peripheral neuropathy is damage to the nerves outside the brain and spinal cord. It affects millions of people in the U.S. It often starts as numb, tingling or burning feet (NINDS - Peripheral neuropathy).
The longest nerves are usually hit first, so symptoms tend to begin in the toes and move up. Later, the fingertips may feel the same. Some people describe it as wearing socks or gloves that are not there.
Not every pins-and-needles feeling is neuropathy. Sitting on a leg or leaning on an elbow can squeeze a nerve for a few minutes. Numbness that keeps coming back, or never fully fades, is the kind worth checking.
Common causes
What are the most common causes of numbness and tingling?
Most cases trace back to a handful of causes, and several of them show up on routine blood work.
Diabetes leads the list, followed by vitamin deficiencies, alcohol and toxins (NINDS - Peripheral neuropathy). Some medicines also play a part, either by harming nerves directly or by lowering B12.
| Cause | What happens | Usual check |
|---|---|---|
| Diabetes | High blood glucose and high blood fats damage nerves over time; one-third to one-half of people with diabetes have neuropathy (NIDDK - Diabetic neuropathy) | A1C or fasting glucose; yearly foot exam |
| Low vitamin B12 | Can cause numbness and tingling even without anemia (NIH ODS - Vitamin B12) | B12 blood test, sometimes with follow-up markers |
| Alcohol | Direct nerve harm plus poor nutrition (NINDS - Peripheral neuropathy) | History and blood tests |
| Medicines | Some cancer drugs harm nerves; metformin and acid reducers can lower B12 over time (NIH ODS - Vitamin B12) | Medicine review with a doctor or pharmacist |
| Other conditions | Thyroid, kidney and autoimmune problems, infections and pressure on a nerve | Blood tests, exam and sometimes nerve studies |
Treating the cause can sometimes let nerves recover (NINDS - Peripheral neuropathy). That is why finding the cause matters more than masking the feeling.
Red flags
When is numbness or tingling an emergency?
Sudden numbness on one side of the face or body is an emergency. With trouble speaking, confusion or weakness, it can mean a stroke. Call 911 right away.
Numbness that spreads quickly over hours or days, new weakness or falls, loss of bladder or bowel control, or a foot wound that is not healing if you have diabetes.
For slower symptoms, a regular appointment is the right step. Numbness and tingling, or memory loss that disrupts daily life, deserves a medical check. Early visits make it easier to find a cause before damage builds.
At the doctor
What tests do doctors use to find the cause?
Most workups start with a talk, a foot and reflex exam and a few blood tests. Nerve studies come later if needed.
History and exam
Where it started, how fast it spread, alcohol use, every medicine and supplement, and a check of feeling, reflexes and balance.
Blood tests
Glucose or A1C, B12, thyroid and kidney function are common first checks (MedlinePlus - Memory loss).
Nerve studies
Nerve conduction tests and EMG measure how well signals travel, if the picture is still unclear.
Tell the doctor if you take a product with B12, such as Neuro Recall. It has 240 mcg per serving. That can raise a blood level and change how a test reads. Bring the bottle so the label is in front of the doctor.
Vitamin B12
Does vitamin B12 help numbness and tingling?
It helps when the cause is a B12 deficiency, and that is the key condition. Low B12 can cause numbness and tingling in the hands and feet, and treating it is a standard medical step (NIH ODS - Vitamin B12).
Without a deficiency, extra B12 is not shown to fix nerve symptoms. The body absorbs only about 2% of a 500 mcg oral dose, and no upper limit has been set because toxicity risk is low (NIH ODS - Vitamin B12).
Folic acid adds a twist. Large amounts can correct the anemia of B12 deficiency but not the nerve damage, so a deficiency can go unnoticed (NIH ODS - Folate). Neuro Recall supplies both, which is another reason to test before you take it. Our vitamin B12 page and folate page go deeper.

View listingAlpha-lipoic acid
What does research show for alpha-lipoic acid?
Studies of IV and oral ALA suggest it may ease nerve symptoms in people with diabetes. Earlier results were mixed (MSK - Alpha-lipoic acid). The common research dose is 600 mg a day.
Neuro Recall lists ALA eighth in a 635 mg blend. By our arithmetic, it can hold at most about 79 mg, well under that dose. ALA can lower blood sugar and add to diabetes drugs. Anyone on those medicines should ask a pharmacist first (MSK - Alpha-lipoic acid). The ALA ingredient page covers the details.
Where Neuro Recall fits
Does Neuro Recall treat neuropathy?
No. Neuro Recall's label makes no nerve claim. The word "nerve" comes from the product name and our domain, not from the bottle. The eBay item specifics mention "Brain & Nervous System Health", which is a listing category, not evidence.
- B12 and folate amounts are printed and fall within safety limits.
- ALA, berberine and chromium are hidden or modest amounts with blood sugar effects.
- No study of the Neuro Recall formula has been published.
- For memory concerns, see our guide to memory changes and warning signs.
Everyday care
What can I do at home while I wait for answers?
Check your feet daily if they feel numb. Wear shoes that fit. Keep blood sugar in the range your doctor sets. Limit alcohol, and bring every bottle you take to your next visit.
FAQ
Numbness and tingling: common questions
What is the most common cause of numbness in the feet?
Diabetes is the leading cause of peripheral neuropathy in the U.S., and one-third to one-half of people with diabetes have some nerve damage. Low vitamin B12, alcohol, some medicines and other conditions are also common. A doctor can sort these out with an exam and blood tests.
Can low B12 cause tingling in the hands and feet?
Yes. A B12 deficiency can cause numbness and tingling in the hands and feet, sometimes before any anemia shows up. Older adults and people on metformin or long-term acid reducers are at higher risk. A blood test confirms it, and treatment is a standard medical step.
Does Neuro Recall help neuropathy?
Neuro Recall is not a neuropathy treatment, and its label makes no nerve claim. It contains B12, which helps only if you are deficient, and a small hidden amount of ALA, likely far below the 600 mg used in nerve studies. See a doctor to find the cause first.
When should numbness be treated as an emergency?
Call 911 for sudden numbness on one side of the face or body, especially with trouble speaking, confusion or weakness, since these can signal a stroke. Get same-day care for numbness that spreads fast, new weakness, loss of bladder control, or a foot wound that will not heal.
Can metformin cause numbness and tingling?
Metformin can lower vitamin B12 levels over time, and low B12 can cause numbness and tingling. Do not stop metformin on your own. Ask your doctor whether a B12 blood test makes sense, especially if you have taken it for years or notice new nerve symptoms.
Is alpha-lipoic acid safe with diabetes medicine?
Alpha-lipoic acid can lower blood sugar, so taking it with insulin or diabetes pills may push levels too low. Nausea is another known side effect. Ask your pharmacist or doctor before adding ALA, or any product that contains it, to a diabetes routine.
