Internal Tremors—-felt by the patient but not seen by others

Fifty years of age, with a multitude of health problems, he appears at the clinic to rule out parkinsonism as the cause of his tremor. Since he began using the CPAP machine to sleep, he has noticed feeling tremulous in the morning. Sometimes the symptom lasts only an hour, but occasionally the feeling stretches out to encompass the entire day. The movement disorder specialist asks what part of the body is affected. With his hand to his chest, the patient indicates he feels the vibrations occurring in his torso, and the movements feel similar to the heart palpitations he’s experienced, though he has asked his wife to touch his shoulder and see whether she can detect the quivering motion, and she feels nothing.
The doctor considers this then gazes at the patient’s medical history. Various practitioners have diagnosed the patient with lupus, myasthenia gravis, and multiple sclerosis- all neurological conditions. The doctor states that lupus can produce a wide range of neurological conditions, and possibly tremor. Diabetics may also experience tremor in an episode of low blood sugar or hypoglycemia, occurring due to an imbalance between insulin or diabetic medication, food consumption and level of exercise and activity. The patient is unable to exercise due to failed spinal surgery. He recounts he has put on eighty pounds because of his immobility. Diabetes as a cause of the trembling doesn’t seem to fit the patient’s description of the action continuing throughout the day.
The specialist relates in a study he is familiar with, people with Parkinson’s disease were asked whether they experienced an internal tremor. Those that reported such a sensation all had depression in common. For people diagnosed with PD, there appears to be a correlation of that symptom and clinical depression. Though the patient lacks slowness, rigidity, and a resting tremor, a course of an antidepressant may alleviate his symptom. The medication the physician has in mind is an old-fashioned antidepressant, Doxepine. However, the medication can’t be given to people with cardiac arrhythmias, which he experiences. Inderal or the generic propanalol is helpful in blocking tremor, though the medication also veils the symptoms that come as a consequence of hypoglycemia; dangerous for a diabetic who may pass out or experience a seizure when blood sugars drop too fast. Depending upon how uncomfortable the tremor is, the physician concedes the whole class of SSRI’s that include Zoloft, Paxil and Prozac are possibilities, if he would like to see whether they calm the symptom. The physician concedes the good news is the patient does not have evidence to suggest he suffers from parkinsonism.
