###Human: Due to cold, I get sound in my ears and jaw. What could it be? ###Assistant: Hi. I understand your concern. Your symptoms suggest a condition called tinnitus. Tinnitus is defined as an auditory perception of internal origins such as a buzzing, ringing, or whistling tone and can be perceived as either pulsatile or non-pulsatile. It can have a significant influence on well-being and performance in daily activities. Your symptoms suggest it is pulsatile in nature. Identification of the underlying cause of pulsatile tinnitus is important for adequate treatment and for prognosis estimation. It can be due to cold and inner ear infection as you also have painful lymph nodes. But you did not mention a fever. If it is infection antibiotics dose will be helpful. Complete and detailed history is essential, which includes possible accompanying complaints like vertigo, hearing loss, ear discharge, and earache. We are worried about an underlying vascular etiology that can be suspected when pulsatile tinnitus is influenced by vascular compression or when a vascular bruit is heard by auscultation. In general, head and neck MRI (magnetic resonance imaging) and CT (computed tomography) provide complementary diagnostic imaging information. I suggest you consult an ENT specialist.
