For the past 2 mornings, I have woken up with a dizzy feeling. I am 25 years old. I have had dizziness before and went to the doctor to find out it was nothing serious. (This was a few years back.) I also had a few spells a few months back and figured it was probably due to a nasty head cold that I was suffering from. I have been good now for about 4 months now and yesterday morning I had a spell and this morning I had a spell. I feel fine when I open my eyes but if I turn on a different side or if I stand up and walk I get all a feeling like floors are shifting. (If I close my eyes it feels like I have spun around in circles really fast.) I don't feel like I am going to pass out or anything and it only happens for a few minutes and then I am good the rest of the day. Just wondering what could be causing this and if I should be concerned? Thank you for your help.
