Have you spoken to your doctor regarding the symptoms? It is not an expected result from the procedure, and you should contact your doctor. It could be a reaction to contrast agent injection that went into your blood stream for the test or something else. Only your doctor with your health history, other symptoms, medication taken, etc. can provide a diagnosis.
Hope this helps, and if you have any new or further evidence, you are welcome to respond. Let us know what the doctor has to say about your very interesting and unusual symptoms. Take care.
