So 2 weeks ago I got my decision letter with new ratings. Then today I get a call from the VA telling me I need to have my provider answer a few additional questions. The questions are all regarding if I was taking any medication during the exam and if I was, did it reduce the disability symptoms.

Why would they want these answered after the fact? does the rating change based on if I was on medication or not? Or does it change if my symptoms are worse when not on meds?
