Last Week I Had What I Think Was Flu. I

Last week I had what I think was flu. I ran fever of 100.4 for few days. Was sick thru Easter. I've had coughing, fever, sneezing some. Whe lying down I hear noises in my windpipe. Like wheezing and high pitched noises. Hard to sleep. I took a Z pack prescribed my my family doctor, But still are having trouble getting strength back plus still hear noises in throat or windpipe.
