i am 24 years old and getting light headed, i have never had this before, i have had it now for a few days constantly, non stop i am getting really worried, as it just happened out of the blue when i woke up one morning a few days a go. When it started it was only when i was moving around and active (even just walking to the toilet, clean house, being on my feet in general. ect.) that i was getting it, and now it is pretty much constant. i have no other symptoms as in feeling nausea (from stressing) or sick, just dizzy/lightheaded all the time. ruled out stress as the cause because i have dealt with stress and anxiety my whole life i get physically sick when anxious or depressed. i have one coffee to wake me up in the morning and it is a routine thing so its not that either. since it started i have made myself drink more water, and i am eating regular and healthily as well. i used to smoke but i quit 3 months ago now and i have even started doing crossfit a couple of weeks ago and i go everyday except now i have started getting this.. I don't feel i can do anything without feeling like i am gonna fall on my face. i cannot study my year 11 and 12 at tafe because i am light headed all the time and not able to concentrate, i am supposed to be getting married in 1 week and a half and i need to be able to sing to my husband on the day but i don't want to forget lyrics or anything like that from not being able to concentrate, i also found out today that i start a job on thursday which i applied for before i started feeling like this! i have a doctors appointment on thursday as well and i hope i can figure this out and go on with my life this is horrible and you don't think about what it would be like until it actually happens. I just want to know if anyone out there has had something like this happen, and if they got any answers. I will also be sure to let everyone know whats going on as soon as i do. Thanks
