Hi all.
Over a week ago i detected a faint pulse in my left ear. That created some anxiety and insomnia. The pulse is very faint and i can easily mask it with white noise, which I do, but I somehow learned to zone into to pulsing sounds externally all throughout my day to day experiences that are generated by outside sources. For example, the shower, the HVAC, the refrigerator in the cafeteria. In all of these locations I can detect audible pulses (with similar tone and frequency) that are clearly coming from external sources (not my head) but they seriously annoy me. It is very difficult to get away from all of these external sources.
How can avoid zoning into external sources of these pulses? I think my fear of something in my head has morphed into a general fear of that sound all throughout environmental stimuli.
