Hello, may I ask how long you have been experiencing these symptoms? It could be related to peripheral nerve or circulatory issues.
If the symptoms are only temporary and you have fully recovered, it should not be a major concern.
However, if your condition does not improve, I recommend visiting our neurology outpatient department for further examination and treatment.
Thank you!

More Info

Unexpected numbness in the hands and feet can be a concerning symptom, and it is essential to understand the potential causes and implications. The sensations you describe—brief episodes of numbness lasting 3 to 5 seconds, akin to an electric shock, along with persistent numbness in the lips—can arise from various underlying conditions.
One possible cause is peripheral neuropathy, which refers to damage to the peripheral nerves. This condition can result from several factors, including diabetes, vitamin deficiencies (particularly B vitamins), alcohol abuse, and certain medications. Peripheral neuropathy often presents with symptoms such as tingling, burning sensations, and numbness, particularly in the extremities.
Another potential cause is anxiety or panic attacks. The body’s response to stress can lead to hyperventilation, which may cause temporary numbness or tingling in the hands, feet, and face. This is often accompanied by feelings of lightheadedness or a racing heart. Given your mention of anxiety and panic, it is possible that these episodes of numbness are linked to your emotional state.

Multiple sclerosis (MS) is another condition that could lead to similar symptoms. MS is an autoimmune disease that affects the central nervous system, leading to a variety of neurological symptoms, including numbness, tingling, and muscle weakness. However, MS typically presents with additional symptoms, such as visual disturbances, fatigue, and coordination problems.
Cervical spine issues, such as herniated discs or spinal stenosis, can also lead to numbness in the hands and feet. These conditions can compress the nerves that travel from the spine to the extremities, resulting in sensory changes.
Additionally, transient ischemic attacks (TIAs) or strokes can cause sudden numbness or weakness in one side of the body. While your symptoms do not seem to indicate a stroke (as you mentioned no weakness or dizziness), it is crucial to be aware of these serious conditions.

Given the complexity of your symptoms, it is advisable to consult with a healthcare professional who can conduct a thorough evaluation. This may include a physical examination, neurological assessment, and possibly imaging studies or nerve conduction tests to determine the underlying cause of your symptoms.

In the meantime, consider keeping a symptom diary to track when these episodes occur, their duration, and any potential triggers. This information can be invaluable for your healthcare provider in diagnosing the issue.

In summary, unexpected numbness in the hands and feet can stem from various causes, including peripheral neuropathy, anxiety, multiple sclerosis, cervical spine issues, and more. A comprehensive evaluation by a healthcare professional is essential to identify the underlying cause and develop an appropriate treatment plan. Remember, early intervention can often lead to better outcomes, so do not hesitate to seek medical advice.
