<s>[INST] I'm a 20 year old female. I have been getting dizzy spells many times a day for 3 years straight. I fell twice in one day sometime in 2013 my body felt as though it couldn't stand up. Everything goes black and my head feels like it's pulsing extremely fast. I fell today and my mom asked if I fell cause there was a bang I couldn't remember falling but I knew I had. What is going on? Is this serious? [/INST] Hello dear,The symptoms as mentioned in your post can be attributed to pathology in the Vestibular Apparatus in inner ear (it is associated with maintenance of body posture & balance) most probably Labyrinthitis or Benign Paroxysmal Positional Vertigo.Symptomatic relief can be obtained with intake of Vestibular sedatives like Betahistine or Cinnarizine preparations (to be taken only under the guidance of a Physician).If it still persists, then you need to consult your Physician/ ENT Specialist & get a complete clinical examination done.Investigations like estimation of blood pressure, blood sugar levels, serum electrolytes & vestibular function tests will be required to rule out any pathological cause for the symptoms.There is no need to worry, you will be fine.Till then, maintain adequate hydration & proper nutrition status and avoid stress.And also take precautions of getting up from bed slowly & avoid sudden head movements.Wishing you a Good Health.Take care. </s>
