Couldn't Agree More, & GOOD FOR YOU! I watched my Husband, Mother, & Brother go to Dr.'s with Blinders On, & all 3 of them are DEAD today! Breaks my Heart that My Husband, an otherwise Intelligent Man, was raised in a Generation that took their Dr.'s advice as "Gospel".
I mentioned to him a couple of times, "Wouldn't you Like to get a 2nd Opinion?" ... He answered, "I'm Using the Dr. that my Other Dr.'s referred me to, That's Good Enough for ME!" (Who Knows, your Dr. may have been referring you to His Brother-In-Law, NOT as skilled as another Dr. available in your Community.)
I've Since come to the Conclusion, "EACH & Every Patient is Like a Snow-flake, No 2 of we patients are Exactly Alike. No - single Dr. can be "All Things To ALL of the PATIENTS (snow-flakes) who walk thru their doors!" If Your 'gut instinct' leaves you insecure, There must be other Dr.'s out there who'd look At You with a Fresh-Different Pair Of Eyes". The 2nd Dr. MAY either Confirm the 1st Dr.'s diagnosis & Convince you that it's the Right course of treatment ... or offer another alternative."
Just 1 Cautionary Note: Don't go to so many Dr.'s that you'll CONFUSE Yourself.

Thank You For Your Wise Words.
You Are So Right about telling 1 Dr. what other Dr.'s said ... It was the 1st time I'd dealt with this Medical Situation. "Ya' Live, Ya' Learn (Hopefully)".
If 2 Mayo Dr.'s advised you to get 2 or 3 Opinions, ESPECIALLY where Major Procedures are involved, I LIKE Their Wisdom! That's Why Mayo has a Reputation as 'One of The Best (IF NOT THE BEST) In The World'.
My Grandfather went to Mayo in the Mid-1930's, after seeing a couple of Local Dr.'s. Mayo Dr.'s "Told It Like It Is, (& IT Turned Out for him ... Just AS They'd told him.)
Good For You for going to Mayo. May I Sincerely Wish You Good Health & A Happy Outcome? & Thank You Again.
