Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Since you're already in the neighborhood, have you tried this group? https://undiagnosed.hms.harvard.edu/. ### Response: UDN is a good thought, and I think worth looking into. I hope this suggestion gets upvoted more. They have great success stories and are run by great people. It also illustrates that "I am at Harvard for medical care" can mean a bunch of different hospitals, clinics, and doctors, who all have varying expertise and areas of focus.However, a couple things to point out:It's a research study, so not the same as "having a doctor." You also need a study recommendation letter from a health care provider."We cannot accept all applicants." Eligible participants "have at least one objective finding." I honestly don't know how they define that, e.g. is weight loss objective enough?"After all of the necessary information is received... it typically takes 6-8 weeks... to decide whether to accept...."They have about 12 clinical sites across the US, not just Boston.Not trying to dissuade OP. If it were me, I would absolutely be looking at UDN. Let them decide whether you're eligible or not. I'm just trying to provide perspective about what to expect..
