My question involves criminal law for the state of: california

2 months ago my brother and I were assaulted, he had some bruises and bumps but in the other hand I had to go to the emergency room ended up being there for 3-4 days. I still need a surgery on my face I have a cheek/nose fracture i cant even get any work done because i dont have any insurance and medical will not approve me bc im 21 years old, so im left with a bill i cant pay.

The bright side to this is that 2 of the guys have been arrested one of them has plead guilty im not sure what the other one has said. I have to attend a hearing pretty soon and I dont have an attorney should i look into getting one, can i sue them and get them to pay my hospital bills and money for pain and suffering.

Im not a gang member or my brother they just did it for no reason, I was left with a big scar in my face do to this incident. also before they started beating us up one of them was telling me he was going to kill me. I tried getting away from this but i couldnt and after the whole thing started I tried to defend my self but I was no match for 4 guys. please help
