Left Back Numbness: Causes and Treatment Options - Neurosurgery

Understanding left back numbness can be quite complex, especially when considering the various factors that may contribute to the symptoms you are experiencing. Based on your description, it seems that you have a history of postural issues, specifically a tendency towards kyphosis and a habit of leaning on your left hand while sitting. These habits can lead to muscle imbalances and strain on the spine, which may explain the discomfort and numbness you are feeling.

The sudden onset of intense cramping and pulling sensations in your left back, followed by persistent numbness in the area, suggests that there may be underlying muscular or neurological issues at play. The fact that these symptoms worsen with certain postures, such as bending forward and then returning to an upright position, indicates that your spinal alignment and muscle function may be compromised.
Your previous evaluations, including physical therapy and electrical stimulation, have not provided lasting relief, which is not uncommon in cases where there are chronic postural issues or mild degenerative changes in the spine. The MRI of your cervical spine showing degeneration at the fifth cervical vertebra could be a contributing factor, especially if there is any nerve root involvement. The symptoms you describe, such as numbness in your left hand and toes, could suggest that there is some degree of nerve compression or irritation, possibly stemming from the cervical spine or even the thoracic region.

Regarding your question about whether this could be related to the thoracic spine, it is indeed possible. The thoracic spine plays a crucial role in the overall function of the upper body, and issues in this area can lead to referred pain or numbness in the back and limbs. If your symptoms persist, it may be worthwhile to consider imaging studies of the thoracic spine to rule out any significant abnormalities.

In terms of treatment options, it is essential to focus on both symptom management and addressing the underlying causes. Here are some recommendations:
1. Physical Therapy: Continue with physical therapy, but ensure that your therapist is focusing on correcting your posture and strengthening the muscles that support your spine. Exercises that promote core stability and flexibility can be particularly beneficial.

2. Ergonomic Adjustments: Make ergonomic adjustments to your workspace and daily activities. This includes using supportive chairs, adjusting your desk height, and ensuring that your computer screen is at eye level to minimize strain on your neck and back.

3. Postural Awareness: Work on becoming more aware of your posture throughout the day. Consider using reminders or apps that prompt you to check your posture regularly.

4. Pain Management: If you experience acute pain, over-the-counter anti-inflammatory medications may help. However, consult with your physician before starting any new medication.

5. Further Evaluation: If symptoms persist or worsen, further evaluation, including imaging of the thoracic spine or even a neurological assessment, may be warranted. This can help identify any nerve compression or other issues that may require more targeted treatment.

6. Lifestyle Modifications: Incorporate regular exercise into your routine, focusing on activities that promote spinal health, such as swimming, yoga, or pilates. These can help improve flexibility and strength, reducing the risk of future issues.

In conclusion, while your symptoms may be multifactorial, addressing your posture, engaging in targeted physical therapy, and considering further evaluations will be key steps in managing your left back numbness effectively. Always consult with your healthcare provider before making any significant changes to your treatment plan.
