Hello dear,
Considering the fact that your
CT scan of brain is normal, any intracranial pathology is ruled out.
Under such circumstances, the symptoms of
dizziness and swelling can be attributed to the impact as well as accumulation of fluid & blood.
The blood cells accumulated are eventually broken down and absorbed in the body. But this is a slow process & takes times to disappear completely.
Till that time, symptomatic relief is obtained by analgesics preparations (like
paracetamol), ice compression & adequate rest.
If it still persists or there are any other associated symptoms like fever,
vomiting,
loss of consciousness, convulsions, etc...then it will be better to consult your Doctor.
Till then, maintain adequate hydration & nutrition status.
There is no need to worry, you will be fine.
Wishing you a good health.
Take care.
