Lower body pain and numbness in the hands?


Hello, doctor.
I previously participated in a running competition, and after finishing the 200 meters, I experienced significant pain in my lower body (from the hips down).
It wasn't just soreness; the pain was intense, so I lay down for a while, and it gradually improved, but I still felt some pain when I stood up.
Then I ran another 400 meters, and when I had 100 meters left, my hands started to feel numb and cold.
I wanted to open my fingers, but I couldn't.
I continued running, and afterward, my lower body still hurt.
Could you explain why my lower body hurts and why my hands are numb?

Dr. Lan Shengxing reply Neurology


Dear BB, based on your age, I can only speculate that this is likely due to muscle tightness from lack of warm-up, as other common causes do not seem to fit.
As for the finger numbness, it may have been caused by hyperventilation at that time.
That's all.

Experiencing lower body pain and hand numbness after running can be concerning, and it's important to understand the potential causes behind these symptoms. Based on your description, there are several factors that could contribute to your discomfort.

Firstly, the intense pain in your lower body after running could be attributed to muscle strain or overuse. When you engage in physical activities, especially if you push yourself beyond your usual limits, your muscles can become fatigued and may experience micro-tears. This is particularly true if you did not adequately warm up before your run. Warm-ups are crucial as they prepare your muscles for the stress of exercise, increasing blood flow and flexibility. If you skipped this step, it could explain the severe pain you felt.

Additionally, the pain you experienced from the buttocks down could indicate issues related to your lower back or hips. Conditions such as sciatica, which is caused by irritation of the sciatic nerve, can lead to pain radiating down the legs. Another possibility is that you may have strained a muscle or ligament in your lower body, which can lead to significant discomfort, especially after a sudden increase in activity intensity.

Regarding the numbness in your hands, this could be linked to a few different factors. One common cause is hyperventilation, which can occur during intense physical exertion. When you breathe too quickly or deeply, it can lead to a decrease in carbon dioxide levels in your blood, causing symptoms like tingling or numbness in the extremities. Additionally, if you were gripping something tightly (like a water bottle or your phone) while running, this could compress nerves in your arm, leading to numbness.

Another potential cause for the hand numbness could be related to your neck or upper back. Poor posture while running or tension in the upper body can lead to nerve compression, which may manifest as numbness in the hands. If you have any underlying cervical spine issues, such as a herniated disc or degenerative changes, these could also contribute to the symptoms you experienced.

To address these issues, consider the following recommendations:
1. Warm-Up and Cool Down: Always include a proper warm-up before running and a cool-down afterward. This can help prevent injuries and reduce muscle soreness.

2. Strengthening and Flexibility Exercises: Incorporate exercises that strengthen your core, hips, and legs, as well as flexibility routines to improve your overall muscle balance and reduce the risk of injury.

3. Posture Awareness: Pay attention to your running form and posture. Ensure that you are not tensing your shoulders or gripping your arms too tightly while running.

4. Hydration and Nutrition: Ensure you are well-hydrated and have adequate nutrition before running. Dehydration can contribute to muscle cramps and fatigue.

5. Rest and Recovery: If you experience pain, allow your body time to recover. Consider cross-training with low-impact activities like swimming or cycling to maintain fitness while reducing strain on your legs.

6. Consult a Professional: If your symptoms persist or worsen, it is advisable to consult a healthcare professional. They can perform a thorough evaluation, including physical examinations and possibly imaging studies, to rule out any serious underlying conditions.

In summary, the pain in your lower body and the numbness in your hands after running could be attributed to muscle strain, nerve compression, or even hyperventilation. By taking preventive measures and listening to your body, you can reduce the risk of these symptoms in the future and continue to enjoy running safely.
