Hi and thanks for the query, The most important thing in your treatment is actually making a proper diagnosis of what you actually have, and being very compliant to treatment. I would suggest a complete gastrointestinal tract evaluation also be done to exclude peptic ulcer disease or gastroesophagal reflux disease. A chest X ray might also be very necessary to exclude a lung infection. Stool examinations and cultures are actually very appropriate. Complete blood counts in search of raised white blood cells could be suggestive of a generalized bacterial infection. You need might need to get a reevaluation from your treating physician for the migraines, and maybe book for an appointment with a psychiatrist for management of anxiety when confirmed. For now, a complete medical examination by your internist of primary care physician might be sufficient. thanks and hope this helps, Luchuo, MD.
