 [ Symptoms ] where can i find information on the health insurance plans available and if we qualify for the new plan [ Disease ] so basically you have an itchy trigger finger sorry all joking aside my hunch is you are experiencing a repetitive motion or overuse injury due to overuse of your hands while working on the computer this symptom should not be taken lightly because repetitive motion injuries only get worse with time not better the sooner you address the underlying cause the better you are smart to be concerned about parkinson is disease but i want to reassure you that no genetic link has yet been established in parkinson is other than in early onset cases still i would suggest making an appointment with your health care provider to try to discover the underlying cause of your twitching finger if it is a repetitive motion issue you can address the problem through ergonomics if it is something else your doctor can help you with treatment options i wish you the best
