What is wrong with us?

I just took a walk that was supposed to be a run with the dog. I made it one block running and had to walk the rest of the five blocks. My lungs are wheezy and I coughed my head off. Three of the five of our family are affected. Coughing and coughing. Then nothing for hours, then coughing and choking. What is up? We have had this for two weeks. Every time I want to go to the doctor we are better. Every time we are sick and I call the doctor we get better for a time., then it's back. We tried cough syrup, Benedryl, Sudafed, Mucinex, Mucinex Cough, Prescription cough syrup, Claratin, Zyrtec. I coughed until my head and neck ached. Now I am not coughing but I feel like there are bubbles in my lungs. Going to call the doctor tomorrow.
