Numbness in the Outer Side of the Left Pinky: Should You See a Doctor?

Loss of sensation on the outer side of the left little finger?

Hello, doctor! A week ago, my mom gave me a jade bracelet to celebrate my acceptance into college.
After the shopkeeper forced the bracelet onto my wrist, I couldn't take it off at all.
I struggled for an entire night but couldn't remove it.
At that time, the base of my thumb and the opposite side of my palm were red, swollen, and bruised.
The skin on the last segment of my little finger feels numb and is hard to the touch.
Now, the outer side of my little finger feels as if it has been anesthetized, and it doesn't feel like my own finger.
I have no sensation when touching its surface, and I can't really feel hot or cold, but I have no issues with strength or bending it, and it looks normal.
Before wearing the bracelet, my hand felt completely fine.
Should I definitely see a doctor in this situation? If I ignore it, will my muscles atrophy? I don't want my parents to know about this.

Hello, based on your description, your symptoms are more consistent with ulnar nerve neuropathy (affecting the sensory area near the little finger).
When the wrist rests on a hard surface like a table, pressure can lead to ulnar nerve neuropathy.
This condition typically causes numbness, and since your symptoms do not affect motor function, the nerve damage appears to be mild.
If the area of numbness does not continue to expand, it indicates that the nerve is healing.

When diagnosing ulnar nerve neuropathy, physicians rely on a detailed medical history and physical examination, paying special attention to the distribution of abnormal sensations such as numbness or pain.
Common diagnostic tests include nerve conduction studies and electromyography, as nerve conduction velocity slows down when the nerve is compressed or entrapped.
In terms of treatment, it is important to reduce nerve compression.
For individuals who frequently rest their elbows or wrists on a table, using a cushion in between can help alleviate pressure.
Other treatment options may include medications such as vitamin B complex and agents to improve blood circulation.
It is advisable to consult with a neurologist or a rehabilitation specialist for further discussion and treatment.
Wishing you good health and well-being.

Best regards,
Dr.

More Info

It sounds like you are experiencing a concerning issue with numbness in your left pinky finger after wearing a tight bracelet. Based on your description, it seems that the bracelet may have caused some compression or irritation to the nerves or blood vessels in your hand, leading to the numbness and altered sensation you are feeling.

Should You See a Doctor?
Yes, it is advisable to see a doctor, especially since you are experiencing numbness and changes in sensation. While it may seem like a minor issue, numbness can indicate nerve compression or damage, which, if left untreated, could potentially lead to more serious complications.

What Could Be Happening?
1. Nerve Compression: The tight bracelet could have compressed the ulnar nerve, which runs along the inner side of the arm and into the hand. This nerve is responsible for sensation in the pinky and half of the ring finger. Compression can lead to symptoms like numbness, tingling, and weakness.

2. Circulation Issues: If the bracelet was too tight, it might have restricted blood flow to your finger, leading to numbness. This can cause temporary changes in sensation, but prolonged restriction could lead to more severe issues.

3. Soft Tissue Injury: The swelling and bruising you described indicate that there may have been some trauma to the soft tissues of your hand. This could contribute to the numbness and hardness you are feeling in your pinky.

Risks of Not Seeking Treatment
- Permanent Nerve Damage: If the numbness is due to nerve compression, failing to address it could lead to permanent nerve damage, resulting in chronic numbness or weakness in the affected area.

- Muscle Atrophy: While it is unlikely that muscle atrophy would occur in just a week, prolonged nerve compression can lead to muscle weakness and atrophy over time if the nerve is not functioning properly.

- Infection Risk: If there is any open skin or if the area becomes increasingly painful, there is a risk of infection, which would require medical attention.

What to Expect at the Doctor's Office
When you visit a healthcare provider, they will likely perform a physical examination of your hand and may ask about your symptoms in detail. They might check for:
- Sensation in the fingers
- Strength in the hand muscles
- Blood flow to the area
In some cases, they may recommend imaging studies, such as an X-ray or MRI, to rule out any fractures or other underlying issues.

Conclusion
While it may feel awkward to discuss this with your parents, it is important to prioritize your health. If you are uncomfortable discussing it with them, consider seeking help from a trusted adult or going to a doctor on your own. Early intervention can prevent potential complications and ensure that your hand heals properly. Remember, your health is paramount, and addressing these symptoms promptly is the best course of action.
