My father has terrible ringing in his ears. It started after he was exposed to a loud noise. He has tried numerous things but no relief. His ENT put in tubes to help with the "stopped up" feeling and then took them out because there was no fluid and they did not help. He has hearing loss and has been on allergy meds. None of this has worked. This constant ringing with is quite loud has also caused depression. I am looking for any help or advice on this issue. Thanks in advance.
