I was thinking about this thread last night, I posted yesterday but...honestly if it were me, I wouldn't be going on that climb especially as your concussion is so new and from the symptoms you are experiencing.

I had a concussion in late March and have been given strict instructions not to climb by my Dr and therapists.

I have terrible headaches and you describe migraines, climbing that high up the mountain is probably not a good idea and I would imagine make everything worse.

You must take good care of yourself, as Klaus mentions, can you not explain everything to the sponsors and wait?

When I even attempt to walk up very steep hills the massive headache and head pressure gets worse.
