Persistent Numbness in the Left Back: Causes and Solutions - Neurology

More Info

---

Understanding persistent numbness in the left back can be quite complex, especially when it has been ongoing for several months. Based on your description, it seems that the numbness began after a specific incident involving lifting a heavy bag of books, which could suggest a potential nerve-related issue stemming from that activity.
The symptoms you are experiencing—numbness extending from the left shoulder blade to the arm, which is exacerbated by certain positions (like sitting or squatting)—could indicate a few possible underlying causes. One common issue could be related to nerve compression or irritation, possibly due to muscle tension or a postural problem that developed after the initial injury. The fact that sitting up straight alleviates the numbness suggests that your posture may play a significant role in your symptoms.

Given that you have already seen doctors and received a diagnosis of neuralgia and neuritis, it is important to consider the treatment options available. Medications such as those you mentioned (Rifampicin, Kangsulong, and magnesium oxide) are often prescribed to manage nerve pain and inflammation. However, if you are not experiencing any improvement after a couple of weeks on these medications, it may be worth discussing with your physician about reassessing your treatment plan.
In addition to medication, physical therapy could be beneficial. A physical therapist can help you with exercises that strengthen the muscles around your spine and improve your posture, which may relieve pressure on the nerves. Stretching and strengthening exercises can also help alleviate muscle tightness that might be contributing to your symptoms.
Another important aspect to consider is ergonomics. If your daily activities involve prolonged sitting or awkward postures, it may be worthwhile to evaluate your workspace and daily habits. Using ergonomic furniture, taking regular breaks to stretch, and ensuring that your posture is correct while sitting can make a significant difference.

If your symptoms persist despite conservative management, further imaging studies such as an MRI may be warranted to rule out any structural issues, such as herniated discs or spinal stenosis, which could be contributing to your symptoms.
In terms of prognosis, many cases of nerve-related numbness can improve with appropriate treatment and lifestyle modifications. However, the timeline for recovery can vary widely depending on the underlying cause and the individual’s response to treatment. It is essential to maintain open communication with your healthcare provider about your symptoms and any changes you experience.
In summary, while your symptoms are concerning and have persisted for some time, there are various avenues for treatment and management. It is crucial to continue working closely with your healthcare team to find the most effective approach for your situation. With the right combination of medication, physical therapy, and lifestyle adjustments, there is a good chance for improvement and resolution of your symptoms.
