Numbness in Left Pinky Toe: Possible Nerve Damage After Long Walk?

The sensation on the outer side of the left little toe has diminished?

Previously, I walked for an extended period in one day, and at that time, I only experienced foot pain and soreness.
Starting the next day, I noticed that the outer side of my left little toe seemed to have some numbness.
When I touched it, I could feel itching in my right foot, but the left foot felt less sensitive, almost as if the superficial nerves were numb.
It’s not completely devoid of sensation, but it has become very insensitive, like there’s a layer of sock in between.
Additionally, if I touch the area where the side of the left little toe connects to the sole of the foot, I feel a tingling sensation in the little toe, as if there’s a nerve that’s affected.
When I put pressure on my left foot, it feels like there’s a "nerve" inside the little toe that vibrates (though I'm not sure if that is actually a nerve).
It has been a month now, and during this time, I haven't walked for long periods again, but the situation seems to remain the same.
Am I experiencing nerve damage from walking too long...?

Hello, it is suspected to be peripheral fasciitis or neuritis.
It is recommended to apply heat or soak in warm water (be careful not to burn yourself) for one week.
If there is no improvement, please consult a neurologist or neurosurgeon.
Best wishes.

More Info

The symptoms you are experiencing in your left pinky toe, including numbness and a sensation of reduced sensitivity, could indeed be indicative of nerve damage or irritation. Given that you recently engaged in a long walk, it is possible that the prolonged pressure or strain on your foot may have led to a temporary condition known as "neurapraxia," which is a type of nerve injury that can occur due to compression or stretching.

The specific area you described, where you feel a lack of sensitivity and a tingling sensation when touching the side of your left pinky toe, suggests that the nerve responsible for sensation in that area may be affected. The lateral aspect of the foot, including the pinky toe, is primarily innervated by the sural nerve and the lateral plantar nerve, branches of the tibial nerve. If these nerves were compressed or irritated during your long walk, it could explain the numbness and altered sensation you are experiencing.

It is also worth noting that conditions such as "Morton's neuroma" or "tarsal tunnel syndrome" can lead to similar symptoms. Morton's neuroma involves the thickening of tissue around a nerve leading to the toes, often causing pain, tingling, or numbness. Tarsal tunnel syndrome occurs when the posterior tibial nerve is compressed as it travels through the tarsal tunnel, leading to symptoms in the foot.

In terms of recovery, many cases of nerve irritation or mild damage can resolve on their own with time and rest. However, since your symptoms have persisted for a month without improvement, it would be advisable to seek further evaluation from a healthcare professional, preferably a neurologist or an orthopedic specialist. They may recommend imaging studies, such as an MRI or ultrasound, to assess for any structural issues or nerve entrapment.

In the meantime, you can take some self-care measures to alleviate your symptoms. These may include:
1. Rest: Avoid activities that exacerbate your symptoms, particularly long walks or standing for extended periods.

2. Ice Therapy: Applying ice to the affected area can help reduce inflammation and numbness.

3. Footwear: Ensure that you are wearing supportive shoes that do not compress the foot or toes.

4. Physical Therapy: A physical therapist can provide exercises to strengthen the foot and improve nerve function.

If your symptoms do not improve or worsen, it is crucial to follow up with a healthcare provider. They may consider additional interventions, such as corticosteroid injections or, in rare cases, surgical options if there is significant nerve compression.

In summary, while it is possible that your symptoms are due to nerve irritation from your long walk, a thorough evaluation is necessary to rule out other potential causes and to determine the best course of action for your recovery.
