HELP! Need help with some lightheadedness.?

hi! Im 15yrs old nad a while back i got light headed right after getting up from the floor 2 fast and stayed like that for bout 1 week. Anyways. I went 2 the docter and she said i had some sort of liquid in my ear so prescribed me some antibiotic. It worked...well sorta. I still got lightheaded for about 2-3sec when i tilt my head in a wiered way. But now, it happens all the time, liek i bend over and when i get up, BOOM, lightheaded / dizzy for about 2 secs then it goes. Im scared that this might be something serious. Anyone ever had something like this? PLZ HELP!HELP! Need help with some lightheadedness.?
Don't be scared, my brother went through this. It sounds like vertigo ! Go see an ENT (Ear, Nose, Throat doctor) There are special excercises that you can do to help you out. Sometimes it lasts a couple of weeks, sometimes a little longer. But it is nothing life threatening. Although I know, you must feel awful right now, it will get better !
lay on your back with your knees bent and have somebody sit on your left side and hold their right hand about one inch away from your butt and hold their left hand one inch above your head. do this for three minutes and then crouch down and stand up quickly to see if you still get dizzy. if so repeat the process.
this is a proven way to thin the blood.
to thicken the blood or to stop bleeding, do the same thing from the right side holding their left hand about one inch away from your butt and holding their right hand one inch above your head.
hundreds of lives were saved during the second world war doing this.
I doubt that masturbation has anything to do with it ...it really sounds like Vertigo....look that up and see if your symptoms are simular to it ...then see a specialist the is and Ears, Throat and Nose Doctor...
