I have intense vertigo episodes at random with lightheadedness. during these, i feel akin to being stoned. what could be the cause?

Vertigo symptoms: Vertigo can often be caused by vestibular dysfunction, however it is not a specific or sensitive symptom. It is important to know what aggravates the vertigo. Is it after coughing and sneezing? How long do the attacks occur for? Is there a head movement or posture associated with an attack? Have you had any recent Trauma? Have you been sick recently? Balanced diet? Talk to your PCP asap
