Hello, Doctor. My father is 46 years old, a BP and diabetes patient. For about 2 weeks now, he is facing Tinnitus in his left ear. The right ear is fine. Now, recently, he has started having severe hypnic jerks due to which he is unable to sleep. He faces those jerks sometimes even when he is awake and sitting. His body has started twitching due to jerks. He has been taking nurokind for past 4 months now as he had cervical spondylitis in his neck. He is presently taking clonazepam and other medicines for vertigo as prescribed by the ent doctors. Are there any chances of him having brain tumor, or is it just because of stress or aging.
