Sorry to hear about your tinnitus folks. Although this is the key question that many scientists and doctors are researching throughout the world, what goes so wrong with our system to produce this symptom permanently!! Man this is extremely overwhelming. Mine was relatively a small hit and bam!! Tinnitus forever!! Isn't this crazy?? Everything else will heal...Even the debilitating headaches cognitive problems or depression may go away at some point ...there are many people cured of cancer too...I understand tinnitus is nowhere near as painful as cancer and is just annoying, but what's so special about this thing that it lasts forever. One event in life will leave back tinnitus for to he rest of our lives! Everything else will pass away, but tinnitus won't. It will be same even 10 years from now and will keep reminding me of this hit always, even decades from now. Wow! This thing must pass away because everything else does! This isn't fair. Life has to move on and we can't spend our life always thinking about this stupid PCS. We need urgent help and a cure fast for this! Sorry for whining, but this is crazy!
