You should definitely talk to a medical malpractice attorney. If a patient is injured due to a medical professional's negligence, or unreasonable carelessness, the patient may be entitled to compensation (including medical costs, lost wages, if any, and possibly pain and suffering for prolonged pain and/or some loss of function). Medical malpractice can come in many forms and at many stages in the medical treatment, such as misdiagnosis; a poorly done surgical proceeding; and also improper follow-up, testing, or monitoring, if the accepted standards of care would have included follow-up, etc. From what you write, it would be worthwhile consulting with a medical malpractice attorney. Don't wait, though; if too much time passes, then the "statute of limitations" will bar you from bringing your lawsuit.
