Hi SunnyDee,
Welcome to the boards and to the great people you will meet here, as I have.

You mentioned that you have been going to doctors for over a year without an official diagnosis. It is good that you are being referred to yet another doctor at Mayo, but I am concerned that treatment for the suspected RSD has not begun. Have you had any treatment, such as meds, physcial therapy or blocks, or alternative treatments such as acupunture, massage.

It is not advised to put ice on RSD sites so keep that in mind, or mention that to your doctors..

It must be intense for you to have developed so many symtoms over the year...I hope you are getting some help with the emotional side of pain mangement ..
Wishing you results in getting a definitive diagnosis soon ,and some relief on the horizon!
Let us know how it goes!
Hope4thebest
