Patient discussion about knife

Q. Should I go for the knife? I have essential tremor for many years, and in the last few years it seems nothing helps it, and although I tried all the drugs my doctor could offer me, nothing helps. It really ruins my life, and recently I read about a surgery that suppose to treat it, called thalamotomy- does anyone know anything about it?

A. It's a possibility, and considered effective (reducing tremor in most of the patients). However, it has quite serious side effects, that can result even in weakness of some parts of your body. You should think really good before you opt for this treatment. Good luck!
