Oh no, thats frustrating that you have to wait longer...hang in there!
As we have chatted before you know I had similar symptoms. I also had the soreness in my chest, esp when I leaned over or lying on my side in bed, but I can say this has improved greatly over time. The tiredness still remains though. When you do finally get to see your cardiologist make sure you tell him everything you are feeling/experiencing.
Hang in there hun..and please let us know how it goes.
