I fell off a 3' tall wall app, 9 months ago, and landed on my right shoulder, and I still have a lot of pain, in my right shoulder and my right hand and arm, continues to tremor, could I have a damaged nerve causing the tremor in the right hand,

Done, MRI, cat and dat scan, the nurelogist, said I had Parkinson's disease , I never had any tremors, until a month or so after I fell off the wall, could this be a pinched nerve
