On the whole, you need to recruit medical malpractice attorney if you have been injured during the surgery, had been put a wrong diagnosis or prescribed the drugs that do not work for you, etc. If you caught an infection while attending a medical professional, you could also contact an attorney. Finally, doctors should always keep their patients aware of the possible threats or outcomes of anesthesia or therapy, for instance. In case you were not informed, you may get compensation as well.
