I hate to tell you, but there is only HOT water coming out of master bath shower. xxx thinks it could be a valve inside faucet but not sure. I have water trickling from that faucet just in case it's a frozen pipe. xxxhas very little experience in this so he doesn't want to risk making it worse. It's -6 degrees today, -25 with windchill.

Like you said, it's -6 outside, so it's most likely frozen pipe, put a heater to it and wait few hours, or use a hair dryer brow hot air to the pipe.
