What Causes Dizziness And Leg Pain?

hi,



i don't know whats causing it at the moment but i keep feeling very faint when i was at work this evening when i turned my head to the right i went really dizzy and when i stood up my legs were like jelly.

I managed to walk home which took me a lot longer than usual and had to sit down for 5 minutes but every time i go to stand up i had to sit back down again.



what could this be this is not the first time it has happened
