can i still sue my former employer after he has taken care of the medical bills for my pain and suffering

It sounds like you would like to receive compensation for pain and suffering.  That's not usually available in a work-related accident because most employers are required to carry workers' compensation insurance.  Florida employers required to carry workers' compensation include an employers with four or more full or part-time employees, construction firms with even one employee and farmers with more than five regular employees and/or twelve seasonal workers.  Under the workers'' compensation statute, you are entitled to medical expenses and wage benefits if you are unable to perform your regular work duties. On the other hand, if you employer was required to carry workers' compensation insurance and failed to do so, you can sue to recover damages for pain and suffering.
