Im sorry you had to go through that.
Your case unfortunately is not unusual.there are incompetent drs and hospitals. We dont have much control over that..your wife was blessed to have you.
We met in a nursing home we both worked at. She was a CNA I worked maintenance. She went quad while we were dating and married in the hospital. I was bleed to have her 30 years. We both had a lot of great compassionate doctors and a couple bad ones usually mental health doctors or related too that. I had PTSD develop about the same time G.A.D. hit me or Generalized Anxiety Disorder they tried to treat with antidepressants. They ignored the part of my medical history showing one eye functioning, Inner Ear issues, and now what is called Central Auditory Processing Disorders. I almost went over the edge with their antidepressant protocols. Finally one doctor understood and said they can't help you and he put me on 0.5MG of Xanax back in 1994. It toned down the myoclonic jerks to a functional level. I'm also at 50% hearing loss and wear hearing aids.
You do hear things with hear aids which can come from radio interference from another electronic device. To me it would sound like a TV on very low in another room unable to understand words. I figure it's likely a plane going over that and this started happening when I was given bluetooth hearing aids about a year ago. Very infrequent occurrences. But I understand enough radio theory to know it can happen. That is what FCC regs are supposed to cover but nothing is fool proof.
