You will need to be examined by another doctor to determine whether or not the anesthesiologist caused your jaw problem.The medical report from the second doctor will be crucial in determining whether or not you have a case for malpractice against the anesthesiologist.Medical malpractice is negligence.  Negligence is the failure to exercise due care (that degree of care that a reasonable medical practitioner in the community would have exercised under the same or similar circumstances to prevent foreseeable harm).Prior to filing a lawsuit for negligence against the anesthesiologist (if the second doctor's report supports such a claim), it may be possible to settle the case with the anesthesiologist's malpractice insurance carrier.  Your claim filed with the the malpractice insurance carrier should include your medical bills and medical reports (especially the report from the second doctor).  Documentation of wage loss (if applicable) should also be included.Compensation for the medical bills is straight reimbursement.  The medical reports will document the nature and extent of your injury and will be used to determine compensation for pain and suffering which is an amount in addition to the medical bills.  Compensation for wage loss is straight reimbursement.If the case is settled with the anesthesiologist's malpractice insurance carrier, NO lawsuit is filed.If you are dissatisfied with settlement offers from the malpractice insurance carrier, reject the settlement offers and file a lawsuit for negligence against the anesthesiologist.If the case is NOT settled, your lawsuit for negligence against the anesthesiologist must be filed prior to the expiration of the applicable statute of limitations or you will lose your rights forever in the matter.
