Welcome

It's good to have you in our community.

A second opinion is always good. Sometimes nerve damage is a known risk of a surgery. Did they tell you that was a risk?

the brachial plexus is a complicated bundle. The phrenic nerve is too. It can take a long time for a nerve to heal. I hope you can recover some from those injuries to your nerves.

Keep us posted on how you're doing as you going through your journery.
