First off, let me just say that any comments and suggestions are deeply appreciated. I've been lurking here, and I've decided to post my own today.
I am a 19 years old college student with no known medical problems, both in myself and in my family. 2 weeks ago, I stayed up pretty late (2AM) and I was lying in bed screwing around on my phone. Suddenly, I had this weird feeling in my head that I never felt before. It's hard to describe, but it was like a sudden rush and my whole head felt warm, fuzzy, and slightly vibrating. My heartbeat got high (as if I just ran a marathon). I freaked out and mom drove me to the ER. On the way there, I felt very lightheaded, as if I was about to faint. They tested my thyroid, urine, and EKG, everything turned out fine except my potassium level was a little low. Doc told me everything was OK, sent me home. Still freaked out, I forgot to ask the doctor exactly why that happened if I was "fine."
Ever since then, I've had it 2 or 3 more times (the most recent one today, in a class). I am a bit of a worrier in the first place, so this has driven me to full hypochondria. I noticed that I get these sensations on the days when I did not sleep well and feel tired.
I want to get more tests done, but the problem is that my family cannot afford insurance, and I hear a full checkup can run you thousands of $$$.
Can anyone offer some insight into this? Have you guys ever felt these rushing sensations too? Is this an anxiety attack, or do you think it's some other underlying medical problem?
Thank you very much!
