Hi @helenstamas, welcome to Mayo Clinic Connect. Might it have been this discussion that you read a couple of years ago?
- Monthly shaking episodes that continue to progress https://connect.mayoclinic.org/discussion/monthly-shaking-episodes-that-continues-to-progress/

I'm glad that you started this new discussion specifically about orthostatic tremor. For people who may not be familiar with OT, here's a great explanation:

Helen, can you share a bit more about yourself? When were you diagnosed with orthostatic tremor? Did it take a while before your were diagnosed? What aspects of the condition have worsened for you over time?
