Hello @susan62 and welcome to Mayo Connect and the Parkinson's (PD) discussion group.
I am glad to see that you will be seeing a neurologist. That is the best type of doctor to sort out your various symptoms. I encourage you to learn as much about PD as you can before your appointment. Here are some links to websites that will help you understand the indicators of PD. The Parkinson's Foundation can be found at this link, http://parkinson.org/. Another great website is the Michael J. Fox website, https://www.michaeljfox.org/.
As you look through these websites you will become familiar with the various symptoms (i.e., loss of smell, taste, constipation, soft voice, swallowing problems, sleep problems, etc.) and you might have more to discuss with the neurologist when you see him/her.
I am currently involved in physical therapy with a PT who specializes in PD. (I usually go to PT at least twice a year in order to keep flexibility and reduction of pain). There are specific ways that they help with the numbness, pain and stiffness. It is most helpful. Massages can also be great way to help with the stiffness and pain.
There are many exercise classes now for people with PD. I go to a PD dance class which is done seated but the music is really great! There are about 10 in our class and we have a great time and feel better when we leave. Here is a website where you can view some Dance with PD videos, https://www.youtube.com/results?search_query=Dance+for+PD. Most classes can be done seated until you are comfortable standing. I still sit for the major portion of the class.
I look forward to hearing from you again. Please feel free to ask any questions that concern you. I'm going to invite some other members to join this conversation, @mariemarie and @ggopher. @mariemarie has been involved in a Pedaling for Parkinson's class for a while now. These classes are offered at various YMCA's and are very helpful to many PD patients. Here is a link to information on those classes, http://www.pedalingforparkinsons.org/
