Thanks for all your duas, everyone.
Update:
Surgery was successful, and he's stable. He's slightly moving his arm and leg, which the doctor said is a good sign. However, they will keep him in the hospital for the next week to ensure things are fine and check for abnormal issues. He will be in a neck brace for three months, after which he will start physical therapy.
1) They placed rods on both sides of the spine from C3 to C6. At first, they were thinking of fusion which is the worst-case scenario.
2) He will take regular aspirin daily to prevent blood clots, especially in the artery area.
This incident will be life-altering as one wrong decision and an irresponsible friend ruined everything. He was very athletic, only 23 years old, and played football from 7th grade to college on a scholarship with an excellent build, which the doctor said possibly helped prevent a complete separation. He was attending the University of Illinois at Urbana-Champaign to finish his master's in accounting and then sit in for the CPA exam. He also accepted a full-time position at Deloitte. All that is now down the drain for him, and I'm sure he is contemplating this while he's drugged up. The doctor even said he kept mentioning his studies and work and told us she told him it's not possible right now.
We now have to see as he heals how his body works and pray no post-op issues, etc.
I always tell my siblings to keep their company clean and professional, and goofballs should not be in the picture past 8th grade.
Instead of my parents relaxing at their age, they now have to care for him rather than being the other way around.
