HI, I recently experienced light headedness and dizzness after having a dinner of pasta. I experienced two more epeisodes on the way home 20 minute drive. . IT is very cold out, and after filling up the car with gas, my chest felt tight and I experienced some light headache on the drive home. My blood pressure afer a little nap, is 95 over 55.
I normally do not have high blood or low blood pressure. Dr. recently put me on blood pressure pill and a water pill for edema in my ankles. Any ideas? Should I be concerned.

My doctor just called me, Thank you for your time....
