Foot and Finger Numbness: When to Seek Medical Help

Finger numbness and foot problems?

On August 26th, I rolled my left foot twice in a row, and since then, I have been unable to lift my left foot while standing, making activities like putting on socks very inconvenient.
When sitting, the situation is slightly better, but I still have significantly less range of motion compared to my right foot, and certain areas of my left foot remain numb.
There is also a noticeable line in the middle of my left foot that my right foot does not have.
Additionally, two weeks ago, I experienced numbness in my right hand after sleeping on it.
Initially, my entire palm was numb, but now it has improved to just my ring finger, although it still feels strange.
I have seen an orthopedic doctor regarding my left foot issue, and he mentioned that it would heal on its own.
However, it has been almost two months now, and I would like to ask if I should return to see a doctor about my issues, or if they will resolve on their own.
If I need to see a doctor, should I consult an orthopedic specialist or a neurologist? Thank you, doctor.

More Info

It sounds like you are experiencing significant discomfort and functional limitations in both your left foot and right hand, which can be concerning. Based on your description, the issues you are facing could potentially be related to nerve compression or injury, particularly given the numbness and the difficulty in lifting your left foot.

Understanding Your Symptoms
1. Left Foot Issues: The inability to lift your left foot and the associated numbness could indicate a problem with the peroneal nerve, which runs down the outside of the leg and controls the muscles that lift the foot. The "line" you mentioned could be a sign of altered sensation due to nerve involvement. If you experienced two "rolls" or sprains, it is possible that the nerve may have been compressed or injured during those incidents.

2. Right Hand Issues: The numbness in your right hand, particularly in the ring finger, could suggest compression of the ulnar nerve, especially if you were sleeping in a position that puts pressure on your arm. This is commonly referred to as "cubital tunnel syndrome," where the ulnar nerve is compressed at the elbow.

When to Seek Medical Help
Given that your symptoms have persisted for nearly two months without significant improvement, it is advisable to seek further medical evaluation. While some minor nerve injuries can heal on their own, the duration of your symptoms suggests that a more thorough investigation may be warranted.
1. Consulting a Specialist: Since your symptoms involve both the foot and hand, you may need to see both an orthopedic specialist and a neurologist. An orthopedic doctor can assess any structural issues in your foot and ankle, while a neurologist can evaluate the nerve function and determine if there is any nerve damage or compression that needs to be addressed.

2. Diagnostic Tests: Depending on the findings during your examination, your doctor may recommend imaging studies such as X-rays or MRIs to assess for any structural abnormalities. Nerve conduction studies or electromyography (EMG) may also be performed to evaluate the function of the nerves and muscles.

Treatment Options
If a nerve injury or compression is confirmed, treatment options may include:
- Physical Therapy: A physical therapist can provide exercises to strengthen the muscles around the affected areas and improve mobility.

- Medications: Anti-inflammatory medications or pain relievers may be prescribed to manage pain and inflammation.

- Bracing or Splinting: In some cases, a brace or splint may be recommended to support the affected limb and relieve pressure on the nerves.

- Surgery: If conservative treatments do not provide relief and significant nerve compression is identified, surgical intervention may be necessary to relieve the pressure.

Conclusion
In summary, while some nerve injuries can heal on their own, the persistence of your symptoms suggests that further evaluation is necessary. It is important to consult with a healthcare professional who can provide a comprehensive assessment and guide you toward the appropriate treatment. Early intervention can often lead to better outcomes, so do not hesitate to seek help.
