What can I do about a misdiagnosis?

Well, if you can find a doctor who will testify that it was a misdiagnosis, then you have the basis for suit. Then, you need to establish that you actually suffered (or likely will suffer) damages as a direct result of the misdiagnosis. If the damages are significant enough to justify an attorney spending a bazillion dollars to litigate the case, then you can proceed with a malpractice action.

First, do what you can medically to get better. If the prognosis is good, a medical malpractice claim may not be feasible. Normally temporary pain and suffering, even for several years, is not enough to make it economically feasible because malpractice cases are so expensive in expert witness costs that you really need catastrophic damages for a case to make economic sense. If it appears that the outcome will be worse than it would have been had a timely diagnosis been made, then you should find a medical malpractice attorney to look at your case. You will still need a medical opinion that the misdiagnosis was a result of negligence. Also, you want a quick opinion as to whether the prognosis is different based on the late diagnosis. I would hope the statute of limitations would not start to run until you discovered the misdiagnosis. However, the other side will argue that you should have realized earlier that there was a misdiagnosis, and argue that the statute of limitations (time in which you have to file a suit) began running in 2010. You have 3 years to file a suit, 2 years if the suit is against a government entity (which is the case with many hospitals a and doctors whose practice comes under the "umbrella" of a hospital.

It takes a medical expert's opinion as to malpractice in order to get through the courthouse doors. Medical malpractice lawyers have such experts available. Consider talking to one.

In order to prove a medical malpractice case, a claimant must prove a failure to conform to accepted practice, resulting in an injury. A bad result is not enough, and if it is a "judgment call" by the doctor, there is no malpractice, even if the doctor made the wrong call. You will need to get copies of ALL of your medical records and have a surgeon review them if he/she is willing to testify that your previous doctor(s) failed to conform to accepted practice, then you have a case.

You will not be able to successfully bring a claim for medical malpractice by yourself, so seek out a good attorney experienced in handling medical malpractice cases. Unfortunately, unless someone will say that the delay in the diagnosis caused a serious aggravation of that condition, no attorney would be willing to handle that based upon the value of the pain and suffering alone.

If you can prove all you say you may have a case. If Mayo says it is malpractice you are in business

You have one year from the discovery of the misdiagnosis to sue a doctor. Claim maybe barred is malpractice occurred beyond 3 years ago.
