Numbness in Hands and Feet: Causes and Concerns for Teens

Numbness in the hands and feet?

Hello, I am 17 years old.
Recently, I often feel numbness in my hands and feet, but it's not very severe, just uncomfortable.
I haven't done anything specific to cause it, and it lasts for a long time.
Could this be related to sitting too long? Is it connected to my previous spinal injury? I've also been experiencing frequent migraines lately, and when I look at things with one eye, part of the image appears distorted and has shadows.
I visited an ophthalmologist who said there was nothing wrong and that it might be related to the migraines.
Can migraines cause these symptoms? Is it serious? Thank you.

Dear high school seniors, the numbness in your hands and feet is likely not significantly related to a spinal issue, unless the symptoms are occurring in the neck area.
This may be associated with prolonged sitting or lack of posture changes.
Additionally, the mention of headaches accompanied by visual disturbances and distortions warrants a visit to a neurologist.
Differential diagnosis should consider typical migraines or other underlying issues.

More Info

Numbness in the hands and feet, especially in a teenager, can be concerning and may arise from various underlying causes. Given your age and the symptoms you describe, it is essential to consider both neurological and musculoskeletal factors.

Firstly, the numbness you experience in your hands and feet could be related to prolonged sitting or poor posture, which can compress nerves and lead to sensations of tingling or numbness. This is often referred to as "paresthesia." If you find that your symptoms worsen after sitting for long periods, it may be beneficial to take regular breaks to stretch and move around. Additionally, maintaining good posture while sitting can help alleviate pressure on your nerves.

You mentioned a previous spinal condition, specifically a spinal defect (spina bifida or a similar issue). If you have a history of spinal problems, it is possible that they could contribute to your current symptoms. Nerve compression or irritation due to spinal issues can lead to numbness in the extremities. It would be wise to consult with a healthcare professional who specializes in spinal disorders or neurology to evaluate whether your past condition is related to your current symptoms.

Regarding your migraine headaches, it is not uncommon for migraines to present with visual disturbances, such as seeing distortions or shadows in your vision. This phenomenon is known as an "aura," which can occur before or during a migraine attack. While migraines can cause a variety of symptoms, including numbness, it is essential to monitor the frequency and severity of your headaches. If you experience significant changes in your vision or if the headaches become more frequent or severe, you should seek medical attention promptly.

The combination of numbness, headaches, and visual disturbances warrants a thorough evaluation. It is crucial to rule out any serious conditions, such as neurological disorders or vascular issues. A healthcare provider may recommend imaging studies, such as an MRI or CT scan, to assess your brain and spinal cord for any abnormalities.

In summary, while your symptoms may be related to posture or previous spinal issues, it is essential to consult with a healthcare professional for a comprehensive evaluation. They can help determine the underlying cause of your symptoms and recommend appropriate treatment options. In the meantime, consider implementing lifestyle changes, such as improving your posture, taking breaks from sitting, and managing stress, which may help alleviate some of your discomfort.
