Hard to say: Each provider has their own routine. I would expect a meet/great & review of you past symptoms and treatments. S/he may choose to adjust your treatment plan based on the findings or schedule more tests, depending on the pattern you have. Sometimes a call to the office staff will provide you with the best idea of what to expect during the visit.
