Hi, I am Dr Mittal. I have read your message. I think I can help you. A per the query, you have reported a sudden onset of vertigo that was started when you were cleaning the house that reduced but persisted when you lie down and gets more as soon as you get up. Now, sudden onset of any neurological symptom suggests a possible stroke. And therefore I suggest that you go to a Emergency room as soon as possible and request an MRI of the brain to make sure that there is no stroke. If there is a stroke, you will need to be initiated for the appropriate medications depending on the type of stroke and also the duration after which you manage to reach the hospital. However, you have not reported any other feature like weakness or imbalance. So there is a possibility that instead of having a central cause of vertigo like stroke, you may actually have a peripheral vertigo like benign positional paroxysmal vertigo. There are simple medicine like betahistine that will need to be initiated. There will also be exercises like Brandt Daroff exercises that the doctors/neurologist will need to teach you. However, since stroke is a more serious condition, and a condition in whose management time is a very crucial factor, I think you should get to a emergency service in a hospital that boasts of a neurologist as soon as possible. Once the stroke is ruled out, then the peripheral causes can be considered and treated. I have tried to make it as simple as possible. I hope that you benefit from the suggestion. Please get to a emergency as soon as possible. In the meantime, try to remain still and in bed so that the episodes of vertigo do not worsen. Avoid sudden jerky head movements. Please note, I have assumed that you have no cardiac issues, no diabetes, no hypertension or any other significant past history, as this has not been mentioned in the query. Best of luck, Dr Mittal
