Nerve Issues: Why Is My Left Leg Numb and Painful?

Numbness in the foot?

Hello, Doctor: When I was 13 years old, I had a car accident.
At that time, my left calf was severely injured, and the small bones were fractured.
I was initially treated at Chengqing Hospital (near Zhongshan Park) and then transferred to 803 Hospital.
They did not perform surgery; I was only put in a cast.
Now I can move and jump, but I don't understand why my left foot has been numb since then.
Lightly touching my left leg makes my heart race uncomfortably.
Sometimes, when I sleep, my leg uncontrollably twitches.
I remember that when I was 19, I had another minor car accident, and my left foot became indented for some reason.
I heard that this might indicate a problem.
When I was around 24, I went back to Chengqing for a blood test related to my condition.
I forgot what the specific test was, but I remember it was very painful.
The doctor mentioned that the artery near my knee was slightly obstructed...
However, I found the doctor's explanations too complex and didn't understand, so I didn't return for follow-up visits.
Will my left foot become more uncomfortable as I age? Am I at risk of amputation? I'm very scared.
Dear Doctor, can you help me? If further tests are needed, could I avoid that painful arterial blood test? (Perhaps I might have consulted the wrong specialty regarding my symptoms!)

Dr. Gao Chunde reply Neurology

The symptoms sound like a sequela of nerve injury known as "Complex Regional Pain Syndrome." It is generally difficult to treat.
As for the second car accident causing a dent, the issue depends on the location of the dent and any accompanying neurological symptoms to determine the cause, such as arterial obstruction.
Professional advice may not be possible.

Hello! Thank you for sharing your concerns regarding the numbness and pain in your left leg. Based on your history of trauma from the car accidents and the subsequent symptoms you've described, it sounds like you may be experiencing a combination of nerve-related issues and possibly vascular problems.

Firstly, the numbness and pain in your left leg could be attributed to nerve damage or irritation. Given that you had a significant injury to your left leg at a young age, it is possible that the nerves in that area were affected. Nerve injuries can lead to symptoms such as numbness, tingling, and pain, which can sometimes feel like a burning sensation. The fact that you experience discomfort even with light touch suggests that there may be hypersensitivity in the affected area, which is not uncommon after nerve injuries.

Additionally, the history of vascular issues, such as the blockage in the artery near your knee, raises concerns about circulation. Poor blood flow can lead to symptoms like pain, numbness, and cramping, especially during physical activity. If the blood supply to your leg is compromised, it could exacerbate the symptoms you are experiencing. This is particularly important to monitor as you age, as vascular conditions can worsen over time.

The involuntary muscle movements you mentioned, such as your leg twitching while you sleep, could be related to a condition known as restless leg syndrome or could be a sign of nerve irritation. This can occur when the nerves are not functioning properly, leading to abnormal sensations and movements.

Regarding your concerns about the potential for amputation, it is essential to understand that while severe vascular issues can lead to complications, early intervention and management can significantly improve outcomes. It is crucial to address these symptoms with a healthcare professional who can provide a thorough evaluation. This may include imaging studies, nerve conduction studies, or vascular assessments to determine the underlying cause of your symptoms.

I understand your apprehension about undergoing painful tests, but it is important to communicate your concerns with your doctor. They can explore alternative diagnostic methods that may be less uncomfortable. Additionally, they can explain the necessity of certain tests and how they can help in diagnosing your condition accurately.

In terms of management, physical therapy may be beneficial to improve strength and function in your leg. A physical therapist can work with you to develop a tailored exercise program that focuses on improving mobility and reducing discomfort. Pain management strategies, including medications or alternative therapies, may also be explored to help alleviate your symptoms.

In conclusion, while your symptoms are concerning, there are steps you can take to address them. It is vital to seek a consultation with a neurologist or a vascular specialist who can provide a comprehensive evaluation and guide you through the necessary tests and treatment options. Early intervention can make a significant difference in your quality of life and help prevent further complications. Please do not hesitate to reach out for help, as you deserve to find relief and improve your overall well-being.
