I am 73yrs. old female, with controlled b/p and glaucoma. for last 6yrs since my retirement, I have noticed a tendency to walk or pull to my left after taking 5 steps My PF took an Mri of the brain, normal. two days ago while sitting I observed a sl. tremor on my right finger, next to the thumb. yesterday, the same thing happen, today I am having the same sl. tremor. Could it be early signs of Parkkinsons?
