The severity of hand tremors depends on the cause, explains MedlinePlus. Most tremors get better when the underlying condition is treated. The most common tremor is the essential tremor, and it involves rapid movements of the hands. This tremor may run in a family.
Relaxation techniques, such as breathing exercises or medication, help clear up hand tremors caused by stress, states MedlinePlus. Getting enough sleep and avoiding caffeine help manage tremors of any cause. For tremors that occur due to medication, the doctor may recommend reducing the dosage, changing medication and stopping the drug. Only a severe hand tremor may need a surgical operation, such as thalamotomy or deep brain stimulation, notes WebMD.
