I am a 66 year old male that got an ear infection last June 2015. I am healthy, normal weight, no high blood pressure etc, etc. The ear infection cleared up but I ended up with tinnitus in my left ear. It sounds like air hissing out of a bicycle tire but at a higher pitch. I wouldn't wish this on my worst enemy as it is annoying, distracting, and almost impossible to get a good nights sleep. Plus there is the anxiety that it will get worse. The weird part is that it comes and goes on roughly a 24 hour cycle. One day I don't have any symptoms and the next day it comes on like gang busters. Back and forth day after day. Another symptom is that if I flex my jaw muscles at the back of my jaw there is a crunching and cracking sound coming out of my left ear. I don't have TMJ. Also I live at a moderate high altitude at around 4,100 ft. above sea level. When I traveled down to see relatives at sea level all the symptoms disappeared. Four days later as I was driving home the higher I got above sea level the symptoms came back. So there is some connection with my tinnitus with atmospheric pressure. Higher atmospheric pressure --------no tinnitus. Lower atmospheric pressure----------tinnitus. Why? Who knows. I went to an ear specialist in Mammoth Lakes, CA.. (7,100 ft asl and my tinnitus was roaring). The doctor examined my ears and found impacted ear wax covering my eardrum. He removed the wax, my hearing improved slightly, but unfortunately my tinnitus didn't go away. He didn't seem interested in any of the above information about altitude and atmospheric pressure or the fact that it comes and goes on a 24 hour cycle. It went in one ear and out the other. No pun intended. Now I have discovered another strange thing. If I wear a wax earplug in my left ear I don't get tinnitus. Also wearing the ear plug I can't induce those cracking and crunching sounds in my left ear. At this point I don't have a clue what is causing this. Could someone please tell me what the hell is going on??? I have told others about this and all I get are stares as if I'm wearing a tin foil hat.
