Sorry to hear this, I know the extra test can be stressful especially when you already have your surgery scheduled. The same thing happened to me when I got my endoscopy done they found ulcers so I had to take meds for 30 days. The day before my scheduled surgery date I had to get another endoscopy and found that the ulcer healed so I was cleared for surgery. Dont get discouraged, its better that you are 100%. I hope all goes well.
