I recommend the Integrative Med department at Mayo Clinic Hsp, Jacksonville FL. Ive had years of weird GI stuff and they were able to nail it where the slew of GI doctors and other specialists (all non Mayo folks) I went to didnt. The number for the Integrative dept appointment line at Mayo is 904-953-0951. I rec Dr. Adam Perlman. I see him and a nutritionist there (Lisa) and the treatment plan they developed for me has improved my physical health to such a degree that friends, family, and colleagues have noticed. If your looking for a straight up "I go to the doctor, get a test, take meds, and am fine" then its not for you. If your willing to go on a health journey that might include things like keeping food logs, etc and you recognize that getting to the root/core/bottom of things is like being a detective then this department is for you. Hands down, they will work like detectives to help figure out what is going on. Bottom line, they are the reason I can go on a hike etc and not have to stress about "where will the bathroom be and how close will I be to it".
Best of luck.
