The facts as you described them leave no doubt that the gastroenterologist committed a malpractice: 1) he failed to correctly diagnose your husband's condition; 2) he prescribed prednisone which would have been absolutely counterindicated for a patient with an abscess; 3) he failed to refer your husband fo a proper treatment of an abscess (which would have been surgical). So, you do have a cause of action against the gastroenterologist for professional malpractice. On the other hand, in pragmatic sense, the outcome of your lawsuit might not adequately compensate your husband and you for the pain and anguish that is, unfortunately, awaiting you both. From your description of the events, it appears that your husband was correctly diagnosed just a few days (a couple of weeks, at most) after he was seen by the gastroenterologist. The gastroenterologist's attorney will argue that his client's mistakes did not cause your husband's illness and did not materially worsen his prospects of recovery; if so, the doctor did not do any harm to your husband, and does not have to pay for his mistakes. Your attorney could interpose some valid counterarguments; and, if the case goes on trial, it all will come down to who will convince the jury. However, if your attorney puts together a convincing case, the doctor and his insurance company are likely to offer you a settlement - which might be substantial or not, but will hardly resemble the judgment you could expect from the court. I would recommend bringing this lawsuit; but, considering that it will be a time consuming and emotionally draining experience at en exceptionally difficult time for your husband and you, you both need to think through this decision. May God give you strength.
