Glad you could make your post. I encourage you to take your recovery patiently because it will take a lot longer than you probably think.
Both my sons were knocked cold road racing. #1 had his in the chicane at Daytona and #2 piled into the air fence lining the NASCAR wall at Loudon.
Neither remembers anything about thier crash or even the day they had them. Both were warned against racing again for several months. After a few days, #2 thought he was feeling better. His brother told him "You won't know what feeling better is like until you really do. That is still months away".
He had that crash in July. He didn't really feel "better" until October.
So take your time and don't do anything that could result in another head blow.
