My mom had 2 episodes of severe vertigo in the last 2 weeks. First one started one morning, and she had to lay in bed for 3-4 hours before it subsided, it kept spinning even when she's lying in bed and not moving.
The 2nd one started during the day when she leaned forward to pick somethign up and felt everything spinning around her. It went away when she keeps her head up, but as soon as her head tilted or leaned forward it would trigger an attack, and each attack lasted for 30 sec -1 min each. And she also felt nauseas during the 2nd one for an entire day. But as long as she keeps her head up without moving the verigo went away, which was not the case in during the first one.
There's NO report of ear ringing or fullness sensation either time.
In addition, 2 years ago she had a similar vertigo attack in which she fainted and woke up after a couple of minutes. There was no fainting in the most recent 2 attacks.
What can it be and what can be done about it?
