Without more information, it is not possible to provide you with a meaningful response. I do practice in this area of the law, so I will try to provide you with some general information. If the use of force occurred during the course of an arrest, your claim would arise under the 4th Amendment. The standard would be whether an objectively reasonable officer confronting the same circumstances would believe that the force used was necessary to accomplish a lawful purpose. Factors relevant to that analysis would include the severity of the crime at issue; whether you were attempting to escape; and the level of threat/force that the officer was confronting.
The officer(s) involved are entitled to raise the defense of qualified immunity. Assuming you can establish a constitutional violation (see above) they would still be immune from suit unless pre-existing law gave them fair warning that their conduct violated the constitution. Finally, Georgia sheriff's are immune from suit in federal court in their official capacity because they are considered state officials under applicable circuit precedent.
As you may gather from this response, civil rights claims are unique and complex. You should only consider hiring an experienced civil rights attorney who has successfully represented individuals against the police in the past.
