It would be advisable to speak with a personal injury attorney. The gas station is liable for your injury based on premises liability since you fell on the premises.When you complete your medical treatment and are released by the doctor or are declared by the doctor to be permanent and stationary which means having reached a point in your medical treatment where no further improvement is anticipated, obtain your medical bills, medical reports, and documentation of any wage loss. Your personal injury claim should include these items.  Compensation for the medical bills is straight reimbursement.  The medical reports will document the nature and extent of your injury and will be used to determine compensation for pain and suffering, which is an amount in addition to the medical bills.  Compensation for wage loss is straight reimbursment.If the case is NOT settled with the gas station's insurance carrier, you will need to file a lawsuit based on premises liability against the gas station prior to the expiration of the applicable statute of limitations or you will lose your rights forever in the matter.
