So so sorry for this challenge that has come to your wife and you. Tell us about the treatments she has undergone. Also list the medications she is taking. You are not alone and this is a wonderful community for support and advice. PCS can be a beast to deal with. There are some very long term people here who have dealt successfully with this condition.

Know that your wife's injury will be unique to her. Take any doctors advice with a grain of salt. I am 7 months post injury and feel I have my symptoms in hand. I may possibly never regain my health as it was pre-injury but I still have a full life.

I found it helpful to identify the various symptoms and there causes. I did not quietly accept the nueros opinion that if I just rested more I would be OK. Presently I am doing PT, counseling with a psychologist and following up back issues with a GP. BTW the best advice I have received did not come from any physician. It came from here, from people who have experienced PCS and met those challenges head on

Welcome, feel free to ask any questions and vent if you need to.
