My Husband Is Recovering From An Embolism In His Femoral

my husband is recovering from an embolism in his femoral artery. This is the second one. the last one was 5 months ago. He had surgery last Thursday. Naturally, I am watching him like a hawk. He is complaining about his hands being cold. I have checked his O2 sats (95) blood pressure 135/75, no fever. no chest or arm pain, no difficulty breathing....just kind of concerned
