Thank you for getting in touch with us. As I see, your husband has had two stents placed in his heart. As he is a diabetic too, he should take special precautions and keep his sugar under control. Diabetes
can lead to destruction of nerve
fibers and patient might not experience pain with heart problems. As you mention, his ears are clogged and he has been able to hear his own breathing. It would be tough for us to comment on that without examining the patient. Clogging of ears will most likely not be related to heart problems. If he has any shortness of breath
, edema, palpitations etc, then you should get in touch with your Doctor as soon as possible. But remember the golden rule. His sugar must be kept in control.
Dr. Gagandeep Dhillon
