I understand your concern and anxiety... possible causes may be underlying anxiety disorder, thyroid disorders,sleep disorders,intentional tremors,certain medications ,cerebellar disorders etc...fallow relaxation techniques like yoga, meditation,avoid alcohol, smoking, coffee, tea...have good sleep and develop healthy food habits..consult nearest neurologist for clinical examination and evaluation they will do the needful.

If your symptoms are of recent onset then avoiding stress and ensuring good sleep by doing Yoga/meditation on a regular basis will help. Otherwise you need the supportive care of a psychiatrist.
