For a few years, I have been getting the occasional ultra high pitched tinnitus which sounds similar to a dog whistle but is only noticeable in quiet enviroments but is worse when I get up in the early hours of the morning to go to the bathroom. However, today I am freaking out. I have been suffering severe sciatica pain in my right leg for nearly a month and I am having sleepless nights with it. Last night, I felt a sore throat coming on in the left side of my throat as if I was coming down with a cold. Anyway, this morning while in bed I started getting tinnitus in my right ear (the ear I have been having the high pitched tinnitus) which sounds like background engine noise on an airliner when in the cockpit. I instantly freaked out and tried putting almond oil in my ear to no avail. Now the sound doesn't seem to be as loud as when it started but I'm still concerned. I am wondering if this could be down to stress as I have been stressed out over my bad sciatica and not sleeping properly or could it be just a symptom of a cold coming on as I have a slight sore throat.
