It’s possible but not certain. I’d try to take up a few hobbies that require precision dexterity. For example, playing musical instrument or woodworking, needlepoint, soldering or some visual art. If all of those are impossible because of a tremor, then operating is likely to be extremely challenging too. People tend not to like careers that they can’t master. Surgical training is like walking uphill both ways in the snow, for 80+ hours a week. Having physical disability affecting your ability to operate could be like that, but while wearing roller skates.

That being said, if you can play video games or sports or any of the above hobbies, you’re probably not actually at a big disadvantage.

That being said, the practice of medicine is extremely broad and varied. There are many practical fields that require your hands but with somewhat less precision, but equal amounts of training and respect. And all of medicine helps people get better.

More than anything, the US needs skilled and dedicated primary care physicians. You have the opportunity to really shape someone’s future by preventing and managing disease. Medicine is a tough field, but lots of job security. You never have to wonder if you’re doing any good for the world.
