Hi, I had gone through your question and understand your concerns.
Many times a minor
head injury or concussion is followed by
post concussion syndrome which consists of mild headache,
dizziness, fatigue and irritability lasting for few weeks to 3 months. At present you have headache and dizziness, so i would advise you:
1. To take enough sleep
2. To take oral nonopioid
analgesic like ibuprofen(400mg) for pain (Consult your physician for prescription)
3. Avoid noisy atmosphere and bright light (Direct sunlight or bright screen of mobile or laptop)
4. Visit nearby emergency department if you develop any of these: Persistent vomiting,
Unconsciousness, Seizures, Weakness on one or both side of body and Severe Headache
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
