If you want the scoop right from Mayo Clinic Pain Rehabilitation Center - Dr. Sletten teaches it's okay to say you are having difficult day. No explanation needed. It's good to have one person that you can talk to honestly but no one else needs to know all the details of what you're going through. He teaches about "pain behaviors" which is anything you do say or think that reminds you of pain, and explains that talking about symptoms accesses your pain pathways and can lead to more pain.

I like to reverse the question by answering I'm fine, or doing well, then ask how are you how , how are the children , how is your new job?
