I would prepare for all my appointment by making a list of the things that I wanted to discuss with my doctor, including new symptoms. Then at the appointment I would just lay it out, open and honest.

If your doctor doesn't take your new symptoms seriously and doesn't actively try to help you with them, then you do need to find a new doctor. I did and after I did my care and my health improved 1000%. Don't underestimate how important it is to have a doctor who takes you and your health seriously. My original primary care doctor when I started treatment for RSD was the doctor I had all my life. He delivered me when I was a baby for goodness sakes. But when he told me that I would have to get used to living my life in a wheelchair...that was it. I was done with him. He didn't care about helping me, only with pumping me with pills and forcing me to do treatments I did not believe in. So I dumped him and got a new doctor who is absolutely wonderful.
