One of the chapters in my book, Apparently Different, involves a doctor who, after years of twisting his neck while performing colonoscopies—looking at the patient, then the machine—wound up with a severe condition called Barrett’s esophagus. It took quite a long time to determine his condition. This condition is considered a “zebra,” a medical term for a very unusual condition. Please call me if you’re having problems finding the best doctors according to your diagnosis. I’m a national company, and I help people throughout the United States. Please call me. Thank you.
