  I am sorry to hear about your injury and hope that you recover fully. More facts are needed as well as evidence preservation which can be discussed in consultation with a Personal Injury attorney who can investigate this matter on your behalf and determine all possible responsible parties rather attempting to pursue this on your own. An experienced professional can guide and advise you and evaluate your claim. However, if you are interested in consulting with one of us, you will have to reach out, as attorneys are unable to directly solicit on this forum. Do not delay so as not to prejudice your rights.

You may have a case. Discuss with counsel here in Florida about possible contingency fee representation.
