5 weeks of wheezing and meds

Easton has been wheezing for 5 weeks today. It is a very audible wheeze. I know I posted all about his bronchialitis back in April. Well, after weeks of breathing treatments it may not be bronchialitis after all. He has been on lots of different meds and breathing treatments. Seen the pediatrician tons of times. Some weeks 2 to 3 times. We went to a specialist last thursday. He had x-rays taken and he also felt strongly that Easton needed to have a procedure done - a bronchoscopy and laryngoscopy. We are having that done in the hospital tomorrow. (he'll be under anesthesia) Of course, I'm a little nervous tonight. Just worrying about my baby. I'm sure everything will go alright. I hope we get some answers tomorrow - as far as what is causing this wheezing.
