I'm sorry your T didn't call you back. It sounds like you made it through the procedure pretty well and now you are left with these feelings that your T let you down and wasn't there for you when you needed him even when he encouraged you to reach out. That's always hard because it creates pain that could have been avoided so easily. Like you said, he probably never got the message from the receptionist and so he probably has no idea that you even called. And I am wondering why he would tell you that he usually calls people back within 5 mins? That just sounds so unreasonable to me. How is that possible? He would have to be right there available and waiting for people to call in order to do that.

Anyway, you might feel better if you call him again and can get some clarification about what happened. Since you don't call him often enough to know if he does this frequently (not calling back). My T is notorious for not returning phone calls and has told me to always have her paged if i need her in the moment. When i do that, i always hear from her within an hour. BTW, great job making it through the biopsy and i hope the results are good news!
