Hy husband has been sick with a sinus infection/head cold for more than a couple of weeks. He has taken Ketek, allerga_d and is still coughing up mucous and sick. He has been c/o having a hard time breating in his chest like he is only getting half of his o2. His is also c/o having swelling in his hands, feet, legs. I have listened to his heart and it skips a beat every so many beats. Do you think it has anyting to do with his sickness or do you think it might be his heart.
