I was diagnosed 8 years ago, and my left side has gotten really bad but I still have no symptoms on my right side. Very strange since everything I have read says that PD always starts on one side of the body and then spreads to the other. My left side got SO bad (dystonia, arm muscle cramps, stiffness, incredible leg pain, resting tremor, plus a host of the non-motor symptoms) that I had DBS surgery in 2010 - but only my right brain. I'm better now. Every time I tell a neurologist that it still has NOT spread to my right side and-don't-you-think-this-is-interesting-shouldn't-it be researched-further, the ho-hum response is always along the line of "well, it probably has, you just don't feel it yet" to "wait 20 years and THEN it'll be worth looking into."
Is there anyone who has had PD for 5 -10 years+ but only has symptoms on one side of your body? I would be interested in knowing. My severe symptoms affect the left side of my face, arm, hand, leg & foot. My right side is fine. Am I the only one to think this is odd? I have no doubt about my original PD diagnosis in 2003 since I responded instantly to PD medication I was given at that time.
