A few weeks ago he had surgery (12 hours) to try and repair some of the nerve damage in his right shoulder and arm. Apparently now, they've discovered he's leaking spinal fluid. He is having surgery today to try and find the leak and repair it.
He has been back in school and doing pretty well. Hopefully this set-back will not further impede his progress. Your prayers are greatly appreciated. Thank you.

EDIT: Apparently I misunderstood what day the surgery would take place. It will be on Tuesday, March 4th.
