Fluttering chest pressure every 2 to 5 min, dizziness, hot flashes, headache... What should I do?

You should be seen. If this is the first time this is happening then, you should get a workup now. There is a chance this could be a benign process but on the other hand you wouldn't want to miss something serious by sitting at home and hoping for it to go away. If you've had this before and seen someone who has worked you up then, perhaps less emergent worries right now but call to your doc in morning worthwhile.
