well, only one ear. Started almost 5 weeks ago, turns out I have tinnitus. Had lots of blood tests and a Brain MRI to rule out all kinds of stuff like Lyme Disease, thyroid problems, Acoustic Neruomas (tumors!!), and everything came back negative. The EENT specialist concluded that my problem is "beyond medical knowledge", swept it into a "viral" sub-catagory, and the end result is "It may go away, it may never go away, we have no idea wtf". I got a noise machine and it helps to sleepi with the ambient noise of ocean waves. Fucking thing sucks.
