### input:
Practically every time I stand up from either semi laying down, laying down or sometimes from even just sitting... I completely black out, close to passing out, I have to completely stop and wait until it passes as I cannot see a thing and my legs get weak.. Some of the time for about 10 seconds as it s easing and stopping I have troubles remembering where I am or what I was doing ... I do also have troubles breathing sometimes that I have been advised is due to anxiety... Which causes me to feel as though I have a tight chest So I am constantly trying to take deep heavy breaths..which also may affect the dizziness, because of too much oxygen going to my head? A lot of Mosquitos live around my house and obviously they all find their way into my house, do any of these symptoms indicate the Ross River Virus?? Help!

### output:

Hello dear,First, please do not get concerned with Ross River Virus disease, it presents with a lot of different symptomatology. 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 Labyrinthine or Benign Paroxysmal Positional Vertigo. Symptomatic relief can be obtained with intake of Vestibular sedatives like Betahistine or Linearizing preparations (to be taken only under the guidance of a Physician). So, kindly consult your Physician/ ENT Specialist & get a complete clinical examination done. Investigations like complete blood count, estimation of 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 HY Chat Doctor. And also take precautions like getting up from bed slowly & avoid sudden head movements. Wishing you a Good Health. Take care.
