My son was shot through his chest and experienced a massive stoke a day later. They performed brain surgery and has brain swelling he is 14 years old?

So sorry to learn of. your son's injuries. It sounds like the gun shot may have caused a clot in his heart or chest which then traveled to his brain. Brain swelling after such an injury would not be uncommon and I am sure his doctors are trying their best to resolve this. It is premature to tell how much residual damage he will sustain, and I wish him the best recovery possible. Don't give up hope.
