This isn't really a criminal defense question. In addition, you haven't indicated what injury resulted from the police's negligence, so I'm not sure anyone could answer your question even if it was in the correct category.
I'm sorry to hear about your concussion, but you can't sue for what could have happened.

Unless you suffered some adverse medical consequence, you don't have any damages, so even if a theory of liability, like failure to provide proper medical care, could be developed, there is nothing to recover, making it unlikely that the situation would justify the time and expense associated with a lawsuit.

I am not a doctor, but I believe that the procedure of waking up a person suspected of having a concussion every 2 hours (or more frequently) is no longer used. Sleep and rest are important for anyone with a concussion (so long as the person doesn't sleep far more than they normally sleep). See the following information: http://www.webmd.com/brain/tc/traumatic-brain-injury-concussion-overview
If you did not slip into a coma or suffer any other injury from the intake staff failing to provide a reasonable amount of appropriate medical care, then you don't have a potentially successful lawsuit.
You should probably focus more of your efforts toward the reason(s) you were taken to jail in the first place. I suggest starting with contacting the State Public Defender's Office to see if you qualify for an SPD-appointed attorney.
If AODA issues and/or anger management issues were a contributing factor in your concussion, you may want to consider getting some appropriate treatment. Seeking out such treatment and starting a treatment program before it is ordered by the Court can go a long way toward convincing the prosecutor and/or judge to go lightly on you with any potential punishment for criminal wrongdoing. When your focus is on correcting what YOU may have done wrong instead of those things that others may have done wrong, you are demonstrating that it will take less punishment to get you back on track towards responsible citizenship.
