On call: What causes shaky hands?
Q . I've started to notice a slight shakiness in my writing hand. Is this just normal aging or should I get my shaky hands checked out?
A. If the shakiness is sudden or recent, you should talk to a doctor. It may be nothing serious—for example, just a reversible side effect from a medication or from too much caffeine. However, tremors could be an early sign of a more serious condition, like Parkinson's disease. In that case, you could benefit from early diagnosis and starting treatment.
