Your appt is tomorrow. Please post results of your visit. Descriptions of the incidents give cause for concern.
A friend recently had some odd episodes that she ignored. Her husband was out of town at those times. Two weeks ago, she had another one; her husband was home, so he took her to the ER.
Diagnosis: major heart attack.
2 arteries were 100% occluded. She had to have 4 stents put in, spent about 1 week in the hospital.
So, please do NOT gloss over anything unusual and don't let others tell you it's perfectly normal. Better to "waste" a few bucks having something checked out than to ignore it, thinking it will go away.
