Thank you for writing!
We cannot help you regarding diagnosis. But initial diagnoses can certainly change. Or you may have more than one diagnosis.
One thing we can help you with is dealing with your digestive distress now, until you can get further help. A website that can help you is from Kate Scarlata who specializes in digestive diseases. You can find her here (copy and paste link)
How long have you been on the medication? Have any symptoms lessened? We look forward to hearing back from you-
