I was diagnosed with asthma 2 years ago at age 42. For the last year I have been coughing, wheezing,having excess mucus,headaches, shortness of breath, and dizziness. Most of the time it comes after I eat or when I sleep at night.I had a for allergy test and found that I was allertgic to gluttens, and I am allergic to cats, dogs, and about 15 different plants. I am suppose to start allergy shots, but wheezing prevents me from getting them. What must I do to stop the wheezing and coughing.
