If you read some people stories with young onset parkinson's there first symtom is usually very easy to remember and they have muitple issues. Trust me I have spend hours on the web reading and trying to self diginose myself. If I could take back the time I first time I typed my symptoms in google I would because it has consumed me and made me think I know more than somebody who has spent there entire life studying these types of things. I also know that having a high level of stress and axenity it only fuels bfs. Yes its very hard to get the thought of having something like PD or Ms out of your head, but you also cant live your life worrying about having something wrong with you expecially when you have a .001% chance of getting it. thats means you have a 99.99% OF NOT HAVING ANYTHING WRONG WITH YOU. In the word of my doctor " the internet has turned everybody in a doctor, nothing is wrong and STAY OFF DR. GOOGLE" I know that its easier said than done to get the thought out of your head about having something wrong with you, but you ( along with myself) have to try and forget about it. Everybody has muscle jolts, its impossible to hold you hands still, fingers move, everybody shakes a little, muscles tire everyday. Put your hands out straight do you hands more? do your fingers twitch back in forth? Im sure they do. Put your hand on your table lift you index finger a little I bet it shakes...these are all normal from what I have read and been told by doctors. in the past year I have thought I had ALS, MS, PD, Brain Tumor, and other things I have already forgotten about. Ive been to multiple doctors, had MRI's blood work, exam after exam and still nothng wrong, but like many of people on here I second guess and still worry about something that might never happen. Yes I still worry about having something wrong with me, do I think I have PD????...prolly not but there is this little voice in my head saying what if?? Its something that I will have to deal with for a long time till I know nothing is wrong.
