why i get skin rash in red after each angiography?

The short answer is yes. In the words of the Mayo Clinic. "High temperatures and high humidity can cause more blood flow to the skin. This causes the heart to beat faster while circulating twice as much blood per minute than on a normal day. The greatest risks are when the temperature is above 70 degrees and the humidity is more than 70%." https://www.mayoclinichealthsystem.org/hometown...#
