can I sue a school

It really depends on why you fell. If you fell because of a substance you may have a viable case. It is possible (but in my estimate not likely) that you have a design defect case. Finally, note that under the Tort Claims Act, you have to file a Notice of Claim within 90 days of the accident, or your cause of action may be barred, so talk to a lawyer ASAP.  You should contact a local personal injury attorney (one in your state).  Personal injury attorneys take  cases on a contingency basis which means you only have to pay if you succeed.  Additionally, initial consultations are free. You can use the "Find a Lawyer" service through this website to research personal injury attorneys. Then, visit each attorney's website and select a firm that has a record of successful verdicts. If you are unable to find a lawyer who meets these qualifications within your state, sometimes you may contact an out of state lawyer who can refer you to a qualified attorney in your state while providing support related to the issues of medicine.

I will do nothing further to protect or preserve your interests in the absence of any additional discussion with you about this matter. John Ratkowitz, Esq.
