I'm licensed in Illinois, but the workers' comp laws in most states allow you to request an independent medical exam if you disagree with your treating doctor's decision. Often there are even further steps you can take, such as making a formal request to change doctors. I would recommend consulting with an attorney before going forward. Find someone experienced and local, and ask for a consultation.
That doesn't sound like negligence, but more information is needed, of course. I would work with a local workers' compensation attorney to try and get a change in physician or pursue other options. I can assist if you'd like...despite being in Atlanta, I have cases in SE Georgia where you are, too.
In order to sue a doctor, you have to show a doctor committed negligence and violated the standard of care of all "reasonable" doctors. In addition you must have damages due to their negligence. Medical negligence cases are hard fought and defended.
You have certian rights under workers compensation. One example is you can request a change in physcians or an IME (independent medical exam).
You need a workers compensation lawyer.
You may want to contact the local bar for a reference.
Make it a great day!
