Amnesia due to a car accident?

On December 2, 2017, I had a motorcycle accident and I can't clearly remember what happened at that time.
The possible cause of the accident might be slipping due to the rain, which led to a fall.
I realized I had an accident because there was significant damage to my helmet, but I had no external injuries to my head.
My motorcycle had scratches, I had bruises on my hands, abrasions with bleeding on my knees, and swelling on the right side of my face.
I also don't remember how I got home (I live alone).
Most of the details of the accident are unclear, but I do remember a couple came to help me, and I didn't respond (to thank them) as they also didn't know.
When I regained consciousness, I found myself sitting on my bed and suddenly felt a lot of pain in my knee, which made me realize I might have had an accident.
Later that evening, I wanted to go to bed early to rest, but even though my body felt very tired, I couldn't fall asleep.
I also felt a heaviness in my head.
I have no issues with my memories prior to the accident, but I can't recall the details of the accident itself.
The reason I was riding my motorcycle was to buy lunch, but after the incident, I found that my takeout had been cold for a long time, which made me realize I had indeed had an accident.
I would like to ask the doctor if this could be a concussion.
Is it okay to take sleeping pills since I need to work?

Hello: In cases of head trauma, the most important factors to assess in the first three days are whether there is any loss of consciousness, limb weakness, fatigue, seizures, or epilepsy, as these may indicate the risk of intracranial hemorrhage.
However, if none of these symptoms are present, the risk significantly decreases.
According to your description, you have no significant issues with your previous memory, except for not recalling the moment of the accident.
Later in the evening, you felt the need to sleep early, but despite feeling physically exhausted, you were unable to fall asleep and experienced a heavy sensation in your head.
Many patients with head trauma do experience such symptoms.
However, you not only did not lose consciousness, but you also did not experience headaches, dizziness, nausea, or vomiting typically associated with concussions; instead, you are facing sleep disturbances.
It may be worthwhile to consult your neurosurgeon to consider medication for sleep disturbances, which could be beneficial.
Best wishes to you.

More Info

Based on the details you've provided regarding your motorcycle accident and the symptoms you're experiencing, it is indeed possible that you are dealing with a concussion, which is a type of traumatic brain injury (TBI). Concussions can occur even without a direct blow to the head, especially in situations where there is a sudden jolt or impact, such as in a motorcycle accident.
The symptoms you describe—memory loss regarding the events of the accident, confusion, a feeling of heaviness in your head, and difficulty sleeping—are all consistent with a concussion. Memory loss, particularly the inability to recall the events surrounding the injury (known as retrograde amnesia), is a common symptom of concussions. The fact that you have a noticeable injury to your helmet suggests that your head experienced significant force, even if you do not have visible external injuries.

In addition to memory loss, other common symptoms of a concussion can include headaches, dizziness, nausea, sensitivity to light or noise, and changes in mood or behavior. The bruising on your knee and the swelling on your face indicate that your body experienced trauma, which can also contribute to feelings of fatigue and discomfort.

Regarding your sleep difficulties, it is not uncommon for individuals who have experienced a concussion to have trouble sleeping. This can be due to a variety of factors, including physical discomfort, anxiety about the injury, or changes in brain function following the trauma. While it may be tempting to use sleep aids, such as sleeping pills, it is crucial to approach this with caution. Many sleep medications can have side effects that may complicate your recovery or mask symptoms that need to be monitored.
Before considering any medication for sleep, it is advisable to consult with a healthcare professional who can assess your condition more thoroughly. They may recommend a period of rest and monitoring your symptoms closely. In some cases, they might suggest cognitive rest, which includes limiting activities that require concentration, such as reading, using a computer, or engaging in strenuous physical activities.

If your symptoms worsen or if you experience severe headaches, repeated vomiting, seizures, or increasing confusion, it is essential to seek immediate medical attention. These could be signs of a more serious condition, such as a more severe brain injury or bleeding in the brain.

In summary, based on your description, it is plausible that you are experiencing a concussion. It is crucial to monitor your symptoms closely and consult with a healthcare provider for a comprehensive evaluation and guidance on managing your recovery. Avoid self-medicating with sleep aids until you have discussed it with a medical professional. Your health and safety should always come first, especially after a traumatic event like a motorcycle accident.
