Toe numbness and lower back pain?


At the beginning of this year, I experienced numbness in my left big toe every morning when getting out of bed.
After an X-ray at the hospital, I was advised to undergo lumbar rehabilitation, which I did for about five months (the treatment ended when the toe numbness resolved).
However, after nearly a month, the numbness in my left foot returned, so I resumed lumbar exercises, starting with a quarter of my body weight.
After two or three sessions, I noticed that my right foot occasionally also experienced numbness (once or twice), and sometimes after sitting for a long time, my buttocks would feel numb as well (once or twice).
Is this situation normal? Is it still appropriate for me to continue with lumbar exercises?

Dr. Wang Zhaomin reply Rehabilitation


If lower limb numbness is caused by lumbar nerve root pathology, it is indeed possible for both sides to be affected, necessitating repeated lumbar traction therapy.
If symptoms persist without improvement, it is advisable to discuss with the treating physician whether further examinations are needed to rule out other causes and to receive appropriate treatment options.

Toe numbness, particularly in the context of back rehabilitation, can be a concerning symptom that warrants careful consideration. Based on your description, it seems that you have been experiencing numbness in your left big toe since early this year, which initially prompted you to seek medical attention. After undergoing a regimen of spinal traction for about five months, the numbness subsided, but it has since returned, and you are now experiencing similar symptoms in your right foot and occasionally in your buttocks after prolonged sitting.

To understand whether this situation is normal, we need to consider several factors related to nerve function and spinal health. Numbness in the toes can often be attributed to nerve compression or irritation, which may arise from various conditions, including herniated discs, spinal stenosis, or other forms of nerve entrapment. Given that your symptoms initially improved with traction therapy, it suggests that there may have been some mechanical component to your numbness, possibly related to spinal alignment or disc pressure on nerve roots.

The recurrence of numbness in both feet, as well as in the buttocks, raises some important questions. It could indicate that the underlying issue has not been fully resolved, or it may suggest that there is a new or ongoing irritation of the nerves. The fact that you are experiencing symptoms in both feet could point towards a more systemic issue, such as a problem with the lumbar spine affecting multiple nerve roots, or it could be indicative of peripheral neuropathy, which can arise from various causes, including diabetes, vitamin deficiencies, or other systemic conditions.

As for whether it is appropriate to continue with spinal traction, this decision should be made in consultation with your healthcare provider. If the traction was beneficial in alleviating your symptoms previously, it may still be a viable option. However, if you are experiencing new or worsening symptoms, it is essential to have a thorough evaluation to rule out any serious underlying conditions. Your healthcare provider may recommend imaging studies, such as an MRI, to assess the state of your spine and any potential nerve compression.

In addition to traction, other forms of rehabilitation may be beneficial. Physical therapy can help strengthen the muscles supporting your spine, improve flexibility, and enhance overall function. It may also include specific exercises aimed at relieving nerve compression and improving circulation to the affected areas.
Furthermore, if you are experiencing numbness after prolonged sitting, it may be helpful to evaluate your posture and seating arrangements. Poor ergonomics can contribute to nerve compression, particularly in the lower back and pelvis. Taking regular breaks to stand, stretch, and move around can also help alleviate symptoms.

In summary, while experiencing numbness in your toes and buttocks can be concerning, it is essential to approach this situation with a comprehensive understanding of your spinal health and nerve function. Continuing with spinal traction may be appropriate, but it is crucial to consult with your healthcare provider to ensure that you are receiving the most effective treatment for your symptoms. Regular follow-ups and possibly additional diagnostic imaging may be necessary to monitor your condition and adjust your rehabilitation plan accordingly.
