Pain extending from the lower back to the hips and legs?


Hello Dr.
Lai,
I have been lifting heavy objects for a long time.
Initially, I experienced soreness in my left lower back extending to my hip and leg, with some discomfort in my calf.
I cannot sit for long periods, and the pain is unbearable.
I have been taking medication, but when I don't take it, I experience pain in my lower back when sitting or trying to stand up straight; I have to slowly straighten up.
The pain persists whether I am sitting or lying down, and turning over in bed is also painful.
Sneezing exacerbates the pain, and I have difficulty putting on socks.
I later went to the hospital for an MRI, which diagnosed a torn cartilage.
The doctor mentioned that the cartilage cannot heal and that physical therapy has not been effective.

However, strangely, in the past week or two, the soreness from my lower back to my hip and leg has decreased, and I can even go without medication.
Only certain movements, such as taking large steps or going down stairs, cause pain, but it is bearable compared to before.
Instead, I have developed numbness in my left foot, especially noticeable in the sole of my foot.
1.
Why has the soreness decreased but the numbness in my foot increased? Is this a sign of worsening condition?
2.
Does my situation require surgery?
Thank you.

Hello:
1.
Your condition, my speculation: The cartilage originally contained moisture, and when it first ruptured, it was highly hydrated.
Over time, it became dry and dehydrated, leading to a reduction in volume.
Additionally, the acute pressure from the ruptured cartilage caused inflammation and swelling of the nerve.
However, after taking anti-inflammatory and pain-relieving medication, the swelling of the nerve gradually subsided, and you no longer felt pain.
Nevertheless, the pressure remains, and prolonged compression has led to nerve damage, resulting in numbness.
Furthermore, as the cartilage becomes dry, hard, and sticky, the nerve compression persists, which may increase the difficulty of any future surgical intervention.
2.
Whether surgery is necessary requires a personal examination of the patient and an MRI.

Best wishes,
Dr.
Lai Chao-Kang, Chief of Spine and Nerve Surgery, Changhua Hospital.

More Info


Lower back pain accompanied by leg numbness can be a complex issue, often requiring careful evaluation to determine the best course of action. Based on your description, it seems you have experienced a significant amount of discomfort, particularly after lifting heavy objects, which has led to a diagnosis of a herniated disc. The fact that your pain has lessened but has now transitioned to numbness in your left foot raises some important considerations.

1. Understanding the Change in Symptoms: The reduction in pain you have experienced could be a positive sign, indicating that inflammation or irritation of the nerve root may be decreasing. However, the emergence of numbness, particularly in the foot, can be concerning. Numbness often suggests that there is ongoing nerve compression or irritation. In your case, the herniated disc may still be affecting the nerve root, leading to these new symptoms. It is crucial to monitor these changes closely, as they can indicate the need for further intervention.

2. When to Consider Surgery: The decision to pursue surgical intervention typically depends on several factors, including the severity of your symptoms, the degree of nerve compression, and the impact on your daily life. If conservative treatments such as physical therapy, medication, and lifestyle modifications have not provided sufficient relief, and if the numbness is worsening or accompanied by weakness, surgery may be warranted. Surgical options, such as a discectomy, aim to relieve pressure on the affected nerve root and can lead to significant improvements in symptoms.

3. Further Evaluation: Given your symptoms and the MRI findings indicating a herniated disc, it would be advisable to consult with a spine specialist or a neurosurgeon. They can perform a thorough evaluation, which may include a physical examination and possibly additional imaging studies, to assess the current state of your spine and the extent of nerve involvement. They will also consider your overall health, age, and activity level when discussing surgical options.

4. Potential for Recovery: Many patients experience significant improvement after surgery, particularly if they have persistent symptoms that do not respond to conservative treatment. However, recovery can vary based on individual circumstances, including the extent of nerve damage and overall health. Engaging in a structured rehabilitation program post-surgery can also enhance recovery and help prevent future issues.

5. Lifestyle Modifications: In the meantime, it is essential to continue managing your symptoms through appropriate measures. This may include avoiding heavy lifting, practicing good posture, and engaging in low-impact exercises that strengthen the core and back muscles. Physical therapy can also provide valuable techniques for managing pain and improving function.

In conclusion, while the reduction in pain is a positive development, the onset of numbness should not be overlooked. It is crucial to seek further evaluation from a specialist to determine the best course of action, whether that involves continued conservative management or surgical intervention. Early intervention can often lead to better outcomes, so do not hesitate to reach out for professional guidance.
