Should I file a malpractice personal injury lawsuit?

Is there a limit to file for malpractice? I am now disabled because of a chiropractor. He has been sued and he lost before. He told me my back was fine, mild arthritic changes. I have all his notes, x-rays and MRIs. I'm still technically under his care as I still owe him money over and above what my insurance paid. I have info from 3 Neurologists that one disc is fractured in two places, 3 herniated disc, two bulging disc, stenosis, and multiple bone spur meant that I should NEVER have been touched by a chiropractor (I have this on tape). I went merrily along not knowing I had a bad back. Until I strained my back and became paralyzed with pain and had to be hospitalized. My current medications to just walk carefully are: Fentanyl, Vicoden, Flexeril, Valium, 4 back injections and compazine for nausea etc.
