Frustrating phone tag with doctor...

I've been dealing with several health issues lately, and it's frustrating when things move so slowly. My family doctor called me a couple of weeks ago to discuss my CT results. I didn't notice until I listened to her message on my VM after work. I sent her a message via our patient portal with the best time to call me. She called me again today when I was at the hospital getting a test done. She told me to send her a message with the best time to call. I told her I was off the rest of the day...I was really hoping she'd call this afternoon. I was exhausted but ditched my plans for a nap, in case she called again. Wishful thinking on my part... One of my issues is intense itching without rash that doesn't respond to antihistamines or anti-itch creams. I've been dealing with this for quite some time. It's at its worst at nighttime...I'm getting maybe 4-5 hrs sleep, hence the reason I was really looking forward to a nap. Late afternoon and I figured she probably wasn't going to call...started crying out of frustration and
fatigue. I desperately need to know what next steps to take, as I can't continue to function like this. I know I'm probably being cranky and unreasonable-- I do like her. It's just so frustrating to have so many more ?s than answers.
I apologize for the long rant. If you've made it to the end, thank you. I just really needed to let off some steam. I know many of you have been dealing with much more complicated issues for longer periods of time. Bless us all on our journeys...
