Does A Fasenra Shot Help To Alleviate Chronic Wheezing?

I have had a cough for 3 weeks now. I also have asthma. I have been on prednisone (40 milligrams every morning) for these 3 weeks. I was diagnosed recently with what is called eosinophilic asthma and am and currently awaiting to start a new shot called fasenra. I have had breathing treatments with a respiratory therapist and still started wheezing within minutes of the breathing treatment ending. I have 3 sinus surgeries in 5 years with tons of polyps. I ve had 3 shots in the last week in my butt of steroids, I do breathing treatments at home even. We have even done a zpac. I also get allergy shots. No matter what my asthma and allergy doctors and emergency doctors try don t seem to be working so this fasnera shot is my only hope but until my insurance agrees to cover it, I m at a loss. Any other suggestions. I m tired of wheezing all day and chronic coughing which has also now given me a hyital hernia. Prednisone is now also given me high blood pressure and my stomach is in pain constantly,
