I've read some of your other posts. I think there is far too little information to give you any worthwhile help. Can you be evaluated by a different doctor?

You are in a chicken or egg conundrum. Which symptom was first? Did you fall because of something else that is presenting as similar to Post Concussion Syndrome?

If it is Post Concussion Syndrome, there is not much that can be done. The tinnitus is very common but untreatable.

The loss of bladder control sounds like a serious nervous system dysfunction.

Did the pain cause you to hold your breath leading to passing out?

Too many questions to answer your question online.

Hope you can find a doctor who takes a more serious interest in your recent symptoms.
