I don’t think it should have anything to do with the angiogram as most of the adverse affects of the procedure occur immediately and they usually are related to the site of the puncture or with the kidneys as the kidneys can get damaged by the dye
. At the most, you can get the kidney
function tests done and if they are normal, there shouldn’t be much to worry about. You also need to get your blood pressure checked as a rise in the BP can cause similar symptoms.
I hope that helps.
