My Husband Had Quadruple Heart Bypass Two Years Ago But

my husband had quadruple heart bypass two years ago but still has extreme pressure that starts in one or both arm pits and goes down his arm to his elbows and sometimes wrists. He explains it like Popeye looks. After a a little while it goes away. He has told his Interventional Cardiologist when he goes for checkups but he told him not to be concerned. Can you shed any light on this problem? Thank you, D. Cooper
