It sounds like a very frustrating situation, especially as you were started on treatment for something that it turns out you may not have. Any time you have a concern about your medical care or health, the best place to start with is a trusted physician, for many people their primary care physician
. In this case, it would be very reasonable for you to schedule an appointment with the gastroenterologist
to go over your concerns, but if you feel that you might be more comfortable talking with someone else, that is also very reasonable. In order to determine what happened, you will likely need to talk through your presentation and then look at your medical record with a physician. You or your doctors can always obtain a copy of your medical record, and hopefully going over everything in a systematic and thorough way will help relieve any concerns that you have.
Overall, a pathology report is often only part of a clinical diagnosis. The pathology findings are put into context with the patient's clinical presentation and other laboratory findings. Sometimes this can lead to some confusion between microscopic findings and an exact diagnosis. However, you certainly do want to feel comfortable with your doctors and with your treatment plan moving forward; scheduling a visit with your doctor
to discuss further is a very sensible place to start.
