My 47 year old husband tore his rotators cuff one week ago. He will be having surgery in the next week or two. Otherwise, he is quite healthy. Tonight, he broke out in a cold sweat, mainly on his head and neck, but some on his arms too. His blood pressure is 132/94, and his heart rate is 72. He took a Percolate, but he is still sweating 2 hours later. Is this something to be concerned about ?
