mom was at drs with wheezy lungs. she has a respiratory infection and is being treated with antibiotic and prednisone. her shortness of breath upon exertion still is here. dr stated it may be the respiratory infection. she is on lasix and had a normal chest xray. she is afraid with this afib condition. i don't know what to do for her. her pulse is in the 80s slight irregular and strong. she is not in heart or kidney failure as they have checked for this. we need support . thank you anyone..
