I think i have had many symptoms of lupus, crohn's or a mixed connective tissue disorder for over a year. can i have one if all tests have been neg.?

Health psychologist: Most lab tests have some degree of error, but they are probably correct. In any case, it might really help to have sessions w/ a therapist specializing in challenging, elusive physical symptoms and medical diagnosis problems. There are many patients who have difficulty finding DX and tx - learning to deal with it is often helpful.
