Post-Traumatic Subdural Hematoma Symptoms After a Car Accident

Intracranial hemorrhage due to a car accident?

Hello, doctor.
I would like to ask about a situation that occurred about a month ago.
I suffered a traumatic subdural hematoma due to a car accident and was observed in the intensive care unit for a few days.
After a CT scan of the brain showed that the bleeding had not increased, I was transferred to a regular ward.
I have since returned home to rest, but I often experience dizziness while walking, and I feel particularly dizzy when lying on my left side.
Additionally, I have intermittent pressure and pain in my forehead and temples, and my left ear frequently has a ringing sound, as if there is a layer of membrane over it.
I would like to know if this could be caused by a blood clot still present in my brain.

It is not necessarily a blood clot; it may be a consequence of head trauma.

More Info

Post-traumatic subdural hematoma (SDH) is a serious condition that can arise after a traumatic brain injury, such as a car accident. It occurs when blood collects between the dura mater (the outermost layer of the meninges) and the brain, often due to tearing of blood vessels. The symptoms and recovery process can vary significantly among individuals, depending on the severity of the injury and the extent of the hematoma.

In your case, the symptoms you are experiencing—dizziness, headaches, and tinnitus (ear ringing)—can indeed be associated with a subdural hematoma or other complications following a traumatic brain injury. Dizziness, particularly when lying on one side, may suggest vestibular involvement or increased intracranial pressure. The sensation of pressure or pain in the forehead and temples could be indicative of tension-type headaches or even post-traumatic headaches, which are common after brain injuries.

The presence of tinnitus can also be linked to head trauma. It may arise from damage to the auditory pathways or inner ear structures, which can be exacerbated by changes in intracranial pressure or blood flow dynamics following a hematoma. The fact that your symptoms have persisted after being discharged from the hospital warrants careful consideration.

While it is possible that residual blood or fluid could be contributing to your symptoms, it is also important to recognize that the brain can react in various ways to trauma, and symptoms may evolve over time. The dizziness and headaches you describe could be due to a combination of factors, including inflammation, changes in cerebrospinal fluid dynamics, or even psychological factors such as anxiety following the trauma.

Given your ongoing symptoms, it is crucial to follow up with a healthcare provider, preferably a neurologist or a neurosurgeon, who can evaluate your condition more thoroughly. They may recommend imaging studies, such as a follow-up CT scan or MRI, to assess for any residual hematoma or other complications. Additionally, they can provide guidance on symptom management and rehabilitation options.

In terms of recovery, many individuals with post-traumatic SDH can experience significant improvement over time, especially with appropriate medical management and rehabilitation. Physical therapy may be beneficial to help with balance and coordination, while cognitive therapy could assist with any cognitive deficits or emotional challenges that may arise.

It's essential to maintain open communication with your healthcare team about your symptoms and any changes you experience. Early intervention can be key in managing complications and optimizing recovery. Remember that recovery from a traumatic brain injury can be a gradual process, and patience, along with appropriate medical support, is vital for the best outcomes.
