aww...googley, I'm sorry about the resident. I guess he or she just freaked out. Hopefully s/he learned from the experience and won't be so flighty the next time. Probably what happened is s/he didn't know what to say and was afraid to say the wrong thing and offend you. But you're right, there's no excuse for that. Even I could handle the situation better, and I'm not even a resident yet. A resident should really be able to handle it.

What chronic condition do you have? Diabetes? See, this is why giving results over the phone is a bad idea, even though patients sometimes push their doctors to do it (and I'm guilty of pushing my doctors to give me results over the phones as well).
