I've had some episodes in the past few years that I don't know the cause of...I didn't realize it was recurring until last week.
I start out feeling just generally unwell for a day or so, then all of sudden I get very dizzy and nauseated, feeling like my head is spinning a hundred miles an hour and get hot and cold. I can't see and I hear a loud ring/ buzz in my ears.
The first time I was walking when it started, and I kept running into walls until I finally laid down, and the dizziness lasted about 15 minutes.
The last time, it was much worse, couldn't get up off the floor for half an hour, and I kept vomiting I was so dizzy, and every few minutes I would pass out briefly for about a minute or so. I was also trying to talk to a friend of mine who was trying to help, and I couldn't seem to talk.
After it's over, I feel tired but completely fine.
I'm just unsure of what this is, and now that I realize it's happened several times, I'm thinking it might be more serious. I'm 28, pretty healthy. Could these be some type of heart problem? The symptoms sound a little like what I've read of angina, but I don't know enough about that to say...
