Hi Elaine
So glad to hear you have been able to rule out any potentially dangerous condition associated with the Essential Myclonus. That must be a small light of relief in the context of everything else you're dealing with.
My nephew (19) has had Essential Tremor since about age 15 which developed as part of a genetic condition - 47XYY Syndrome. It got so severe he now has to take beta-blockers to reduce the tremors enough to manage daily functions but he is doing well enough to maintain his studies.
Hopefully your tremor continues to 'behave' itself and remain manageable without medication.
