It sounds like you need to see someone that can accurately diagnose you and give a treatment plan to start out with to see how you progress. If you don't have permenant damage caused by the injections I'm not sure how much good it will do you to hire an attorney and it may create difficulty with your finding a new treating physician as the potential new doctor may want to steer clear of any pending litagation because you're going after a doctor not a corporation or a business or a motor vehicle (driver) etc. That is at least if you are in the USA and contemplating a lawsuit.

I could be wrong but that's just my 2 cents. I'd try to get seen, diagnosed properly and adequately/properly treated before dealing with litagation unless you have some permanent damage that can proven to be caused by the other doctor's treatment.
