Having previously been fit and healthy I have Just been diagnosed with bx after 3 emergency admissions in 2 weeks. Can only keep breathing with steroids every time they stop them I can't breath again. Had lung function tests today and they were pretty good FEV 86% and oxygen saturation 98% on air but I still feel I have to work hard to breath. I'm panicky and frightened. Can anybody out there give me any encouragement?
