Nerve Pain: Is It Related to Disc Herniation or High Arches? - Neurology

More Info

---

Understanding nerve pain, particularly in relation to conditions like disc herniation and high arches, can be quite complex. Based on your description, it seems you are experiencing a combination of symptoms that could be influenced by both your diagnosed disc herniation and your high arches.


Disc Herniation and Nerve Pain
Disc herniation occurs when the inner gel-like core of a spinal disc bulges out through a tear in the outer layer. This can lead to compression of nearby nerves, resulting in pain, numbness, or weakness in the areas served by those nerves. In your case, the left foot's third toe experiencing persistent numbness could be a direct result of nerve compression due to the herniated disc, particularly if the herniation is affecting the nerve roots that innervate that part of your foot.


High Arches (Pes Cavus)
High arches, or pes cavus, can lead to a variety of foot problems, including pain and discomfort in the foot and lower leg. This condition can alter the way weight is distributed across the foot, potentially leading to increased strain on certain muscles and tendons. The symptoms you describe, such as the variability in numbness and pain between your left and right legs, could be exacerbated by the mechanics of high arches. When your foot structure is altered, it can lead to compensatory changes in posture and gait, which may further aggravate nerve pain or discomfort.


Interaction Between Conditions
The interplay between your disc herniation and high arches may be contributing to the symptoms you are experiencing. For instance, if your left foot is more affected by the herniation, you might unconsciously adjust your gait to relieve discomfort, which could lead to increased strain on your right leg and foot. This compensatory mechanism could explain why you experience numbness in your right calf and foot when your left foot is less painful.


Treatment Considerations
1. Physical Therapy: Continuing with physical therapy is crucial. It can help strengthen the muscles around your spine and improve your overall posture, which may alleviate some of the pressure on the affected nerves. Your therapist can also provide exercises tailored to your high arches to help improve foot mechanics.

2. Orthotics: Since you have high arches, custom orthotics can be beneficial. They can provide better arch support and help distribute pressure more evenly across your foot, potentially reducing discomfort and improving your gait.

3. Stretching and Core Exercises: Engaging in stretching exercises and core strengthening (like Pilates) is generally beneficial. However, if you find that certain movements exacerbate your symptoms, it may be wise to modify those exercises or consult with your physical therapist for alternatives.

4. Monitoring Symptoms: Keep track of your symptoms. If you notice a significant increase in pain or numbness, especially if it becomes more consistent or severe, it may warrant further evaluation by a healthcare professional. This could include imaging studies to assess the status of your disc herniation.

5. Consultation with Specialists: If your symptoms persist or worsen, consider consulting a neurologist or an orthopedic specialist who focuses on spine health. They can provide a more comprehensive evaluation and may suggest additional interventions, such as injections or, in some cases, surgical options if conservative treatments fail.


Conclusion
In summary, the relationship between your disc herniation and high arches is likely contributing to your symptoms. Continuing with physical therapy, using orthotics, and being mindful of your body mechanics will be essential in managing your condition. Always communicate openly with your healthcare providers about your symptoms and any changes you notice, as this will help them tailor the best treatment plan for you.
