I Have Been Having Usual Heart Pain That Comes And

I have been having usual heart pain that comes and goes. I have to wait until March to get to see a primary care physician.
I was diagnosed with a prolapsed heart valve as a kid. Later on I was told I didn't have one. My symptoms are heart pain, muscle spasms above heart followed by like a vibration circling feeling in my heart. Any ideas what it could be? Seems like when I'm stressed out it happens more often.
