Hi rc purvis,
Thank you for your question and for being a part of the EmpowHer community. I did a little research, and found that essential tremors (ET) can progress to disability, but according to the Mayo Clinic website, ET does not cause other health problems:
However, your doctor knows your particular case. Are you receiving ongoing treatment? I found this organization, it may be a good resource for you in addition to EmpowHer: http://www.essentialtremor.org/SiteResources/Data/Templates/t2.asp?docid=541&DocName=Facts%20about%20ET
Good luck, and please let us know if there is anything else we can do to help.
