Hello. Thanks for asking from HCM. I can understand your concern. Head injury can cause headache and vertigo for sometime. Important point is to differentiate between dangerous and mild head injury. Because dangerous injury needs medical attention on emergent basis. Mild injury can be managed at home with rest and painkillers. You have to observe few signs of dangerous head injury ; vomiting ; loss of consciousness for more than 5 minutes or decreasing consciousness ; bleed through nose/ear/throat ; fits ; persistent headache not responding to painkillers ; vertigo with confusion, altered behaviour If you are having any of above symptom, you should consult doctor as soon as possible. The doctor might advise CT head to rule out fracture or brain bleed. Further treatment will be decided according to CT report. As you are having dizziness only, you and your family should observe for confusion/altered behaviour as it suggests urgent medical attention. If there is no above sign and your dizziness is decreasing or responding to medication, you can wait and observe at home. For relief, you can follow few tips ; take rest ; avoid pressure at injury site ; apply icepacks at injury site ; you can take Diclofenac sodium after proper prescription ; maintain adequate hydration ; you can check BP to rule out hypotension (SBP Hope it will help you. Still no relief, you can consult doctor. Thanks. Take care.
