So I had the hearing go out on me even before my concussion I think this is normal. Only cause my child said she's had that too. Panic attacks I've had before too but nothing like the ones I get now. I've almost related then to a healing thing. Like as my mind gets better I'll have a huge panic attack. So yes those two things we have in common. Hope you feel better soon, as I hope for my self. Merry Christmas! ]
