Numbness in the hands and feet?

Hello, doctor.
I often experience numbness in my hands (sometimes extending to my wrists) or feet (approximately up to my ankles) during the winter and spring seasons, but my hands and feet do not feel cold.
I would like to know what might be the cause.
Thank you, doctor.
P.S.
I have a history of hypertension, and my doctor has prescribed me half a tablet of Dapoxetine to take daily.

Hello Mr.
Tuna: You mentioned that your hands (sometimes extending to the wrist) or feet (approximately up to the ankle) experience numbness, which may require ruling out peripheral nerve compression issues, such as carpal tunnel syndrome.
Symptoms of peripheral nerve compression are commonly characterized by: 1.
Pain that is burning or tingling in nature.
2.
Symptoms that have a specific band-like distribution, which can be triggered by touch or pressure.
3.
Accompanied by muscle weakness or fatigue.

Examinations for peripheral nerve issues typically involve electrophysiological tests to assist in diagnosis.
Nerve conduction studies assess the conduction velocity and waveform of large fiber nerves.
Electromyography (EMG) evaluates muscle responses in the areas supplied by the affected nerves.
I recommend that you visit a neurology clinic for further evaluation and follow-up.
Thank you for your inquiry, and feel free to discuss further.
Wishing you good health and peace.

Dr.
Jiang Junyi, Neurology Department, Taoyuan Hospital, cares about you.

More Info

Numbness in the hands and feet can be a concerning symptom, especially when it occurs frequently or during specific seasons like winter and spring. The fact that you experience numbness without accompanying coldness in your extremities is an important detail that can help narrow down potential causes.
There are several possible explanations for your symptoms. One common cause of numbness is peripheral neuropathy, which refers to damage to the peripheral nerves. This condition can result from various factors, including diabetes, vitamin deficiencies (especially B vitamins), alcohol use, and certain medications. Given that you have high blood pressure and are taking medication (Dopamine), it’s essential to consider whether your medication could be contributing to your symptoms. Some blood pressure medications can have side effects that include numbness or tingling sensations.

Another potential cause of numbness is poor circulation. While you mentioned that your hands and feet do not feel cold, it’s still possible that there could be intermittent issues with blood flow, particularly if you have a history of hypertension. Conditions such as Raynaud's phenomenon can cause numbness and tingling in response to cold or stress, even if the extremities do not feel cold to the touch.

Nerve compression syndromes, such as carpal tunnel syndrome or tarsal tunnel syndrome, can also lead to numbness in the hands and feet. These conditions occur when nerves are compressed in their respective tunnels, often due to repetitive movements, prolonged positions, or swelling. If you have a job or hobbies that require repetitive hand movements, this could be a contributing factor.

Additionally, anxiety and stress can manifest physically, leading to symptoms like numbness or tingling. If you find that your symptoms are exacerbated during stressful times, this could be a contributing factor.

Given your symptoms and medical history, it would be prudent to consult with a healthcare professional. A thorough evaluation, including a physical examination and possibly nerve conduction studies or blood tests, can help determine the underlying cause of your numbness. It’s also essential to monitor your blood pressure and discuss any concerns about your medication with your doctor, as they may need to adjust your treatment plan based on your symptoms.

In the meantime, consider lifestyle modifications that can improve circulation and nerve health. Regular exercise, maintaining a healthy diet rich in vitamins and minerals, and managing stress through relaxation techniques can be beneficial. Additionally, ensure that you are staying hydrated, as dehydration can also contribute to nerve-related symptoms.

In summary, while there are several potential causes for the numbness in your hands and feet, it is crucial to seek medical advice to identify the specific reason for your symptoms. Early intervention can help prevent further complications and improve your quality of life.
