Maybe both : See your doctor to find out what's going on with you.

Yes: Yes, your symptoms may be part of some panic attacks, seizures, low blood sugar, as well as other treatable conditions. Can you try going to your local medical doctor to have a complete evaluation to determine what's wrong? He or she may want to perform some tests. Good luck.
