Post-Car Accident: Sensory Loss and Recovery

Does a car accident cause sensory loss?

Hello Dr.
Yeh, I’m not sure if this question falls under the scope of neurology, and I apologize if I’m mistaken.
I was involved in a car accident on the morning of May 24th (the car tipped to the right).
I landed on my buttocks first, and then my head hit the ground.
At that moment, I was unable to get up or walk on my own.
I went to the hospital immediately, and the examination revealed a concussion and a dislocation at the end of my coccyx (the doctor mentioned it was somewhat similar to a fracture), but surgery was not necessary as my body could heal itself, so I returned home to rest.
After returning home, I found it difficult to sit or lie down without leaning to one side, relying on the flesh on both sides.
Walking and going up and down stairs caused pain, which I understand is normal.
However, on the evening of May 25th, while showering, I noticed that the sensation on the right side, from the outer labia to the groin area, was significantly less than on the left side, almost as if I were touching it through thick clothing.
During my hospital visit, the doctor mentioned that the sudden impact could cause muscle weakness, but it has been four days, and the sensation on the left side has not improved.
I’m unsure of the reason for this.
Do I need to seek medical treatment? If so, which specialty should I consult? I apologize for asking so many questions, and I appreciate your help.
Thank you!

Hello, if the described tactile sensation (on the right side) is diminished, are the sensations of warmth and cold also abnormal? If so, it may indicate nerve damage, and a detailed examination by a neurologist is necessary.

More Info

After a car accident, experiencing sensory loss, particularly in the context of a head injury and trauma to the lower body, can be concerning. Based on your description, it seems you have sustained a concussion and possibly a tailbone injury, which can lead to various complications, including sensory deficits.

Understanding Sensory Loss Post-Accident
Sensory loss, especially in the context of trauma, can occur due to several reasons:
1. Nerve Compression or Damage: The impact from the accident may have caused compression or damage to the nerves that supply sensation to the affected areas. This can happen if there is swelling or bruising around the nerves, or if the nerves were stretched or torn during the impact.

2. Spinal Cord Injury: Given that you mentioned a tailbone injury, it’s essential to consider that trauma to the lower back can affect the spinal cord or the nerve roots that emerge from it. This can lead to altered sensation in the lower body, including the groin area.

3. Reflexes and Muscle Control: The sudden impact can also affect muscle control and reflexes. If the muscles are not functioning correctly due to nerve involvement, this can lead to a sensation of numbness or altered sensation.

Recovery and Monitoring
In most cases, sensory loss following a concussion or minor trauma can improve over time as the body heals. However, it is crucial to monitor your symptoms closely. Here are some steps you can take:
1. Follow-Up with a Specialist: Since you are experiencing persistent sensory loss, it is advisable to consult a neurologist or a physical medicine and rehabilitation specialist. They can perform a detailed neurological examination and may recommend imaging studies, such as an MRI, to assess for any underlying issues.

2. Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can help you with exercises that may improve strength and sensation in the affected areas. They can also provide modalities that may help with pain management and recovery.

3. Pain Management: If you are experiencing significant discomfort, discussing pain management options with your healthcare provider is essential. This may include medications or alternative therapies.

When to Seek Immediate Care
If you notice any of the following symptoms, you should seek immediate medical attention:
- Worsening numbness or weakness in the legs or groin area.

- Changes in bowel or bladder control.

- Severe pain that does not improve with rest or medication.

- Any new symptoms such as dizziness, severe headaches, or changes in consciousness.

Conclusion
In summary, while sensory loss after a car accident can be a temporary issue related to nerve compression or trauma, it is crucial to monitor your symptoms and seek appropriate medical care. Consulting with a neurologist or a rehabilitation specialist will provide you with a clearer understanding of your condition and the best course of action for recovery. Remember, your health and safety are paramount, and addressing these symptoms early can lead to better outcomes.
