I suffered a car acident approx 18 months ago, as a result of this I have ended upwith a diagnosed essential tremor.

My question is can this tremor have been brought on by the car accident or could there be another possible reason? my symptoms are: shaking hands left worse than the right, GP has given me BETA blockers which I am reluctant to take but seem to control the shake, However I never had this problem before this accident.

Kind Regards
