I am having weird feelings after having two snyope. Get really weak and nervous. Also have heart arrhythmia. Should I be concerned? See nero on fri.

See heart doc too. Since you mentioned having arrythmias which may have been the cause of your syncope, you should get this checked out. After having passed out 2x and having heart arrythmias, i would feel worried too. It is a normal reaction. Your neuro doc sure will want your heart checked out too. Good luck.
See a Cards. You should see a cardiologist as well, may need tilt table testing, holter/ event monitor.
