Leg Numbness After Back and Hip Injuries

Numbness in the lower leg below the knee?

Dear Dr.
Jiang Junyi,
Symptoms: Four days ago, I was accidentally knocked down by a metal door that fell on my lower back.
At that moment, I got up and felt fine.
Two days ago, while lifting heavy objects, I experienced a similar strain in my lower back.
Yesterday, I accidentally slipped in the bathroom and landed on my right buttock.
Today, upon waking up, I noticed that my right calf below the knee has started to feel numb, and after walking for about five minutes, the numbness intensifies.
The numbness and pain only subside when I lie completely flat.
Could you please advise on what might be the issue or what detailed examinations I should undergo? Thank you.

Hello, based on your description, it may be necessary to consider symptoms of sciatic nerve compression due to a herniated disc.
A herniated disc can also occur due to sudden injuries, such as twisting the waist suddenly, bending to lift heavy objects, or experiencing excessive force, for example, falling from a ladder or landing directly on the spine.
If a herniated disc occurs, it may cause localized inflammatory responses leading to back pain, and it can compress the nerve roots, resulting in numbness and pain radiating down one leg.
Typically, a physician can arrange for nerve conduction studies or electromyography to determine if there is nerve damage.
Imaging studies can also be arranged to confirm whether the herniated disc is causing nerve root compression.
It is recommended that you visit a rehabilitation department or a neurology or neurosurgery clinic for further evaluation.
Wishing you good health and peace.
Dr.

Dear 江俊宜,
Thank you for reaching out with your concerns regarding the numbness in your right leg following a series of injuries. Based on your description, it seems that you have experienced multiple incidents that could contribute to your current symptoms, including being pressed by a heavy door, lifting heavy objects, and slipping in the bathroom. Each of these events could potentially lead to various musculoskeletal injuries, particularly in the lumbar spine and hip region, which may be affecting the nerves that innervate your leg.

The numbness you are experiencing in your right calf, particularly after these incidents, raises a few possibilities. One common cause of leg numbness following back or hip injuries is nerve compression or irritation. This can occur due to a herniated disc in the lumbar spine, which may press on the nerve roots that exit the spinal column and travel down the leg. Additionally, muscle spasms or inflammation in the lower back or hip region could also contribute to nerve irritation, leading to symptoms like numbness or tingling.

Given that you mentioned the numbness is alleviated when lying flat, this could suggest that certain positions may be relieving pressure on the affected nerves. It is essential to consider that prolonged pressure on nerves can lead to more severe symptoms, including weakness or loss of function in the affected leg.

To address your concerns, I recommend the following steps:
1. Medical Evaluation: It is crucial to consult a healthcare professional, preferably an orthopedic specialist or a neurologist, who can perform a thorough physical examination. They will assess your range of motion, strength, and reflexes in your legs and back.

2. Imaging Studies: Depending on the findings from your physical examination, your doctor may recommend imaging studies such as X-rays or an MRI of your lumbar spine. These tests can help identify any structural issues, such as herniated discs, spinal stenosis, or other abnormalities that could be causing your symptoms.

3. Conservative Management: In the meantime, you may benefit from conservative management strategies. This can include rest, avoiding activities that exacerbate your symptoms, and applying ice to reduce inflammation. Over-the-counter anti-inflammatory medications may also help alleviate pain and swelling.

4. Physical Therapy: Once you have been evaluated, physical therapy may be recommended to strengthen the muscles around your spine and improve flexibility. A physical therapist can guide you through exercises that promote spinal stability and reduce the risk of further injury.

5. Monitoring Symptoms: Keep a close watch on your symptoms. If you experience worsening numbness, weakness, or any new symptoms such as bowel or bladder dysfunction, seek immediate medical attention, as these could indicate a more serious condition requiring urgent intervention.

In summary, your symptoms of leg numbness following multiple injuries warrant a comprehensive evaluation to determine the underlying cause. Early intervention is key to preventing potential complications and ensuring a full recovery. Please prioritize seeking medical attention to address your concerns effectively.

Wishing you a speedy recovery and good health.
