I have just completed my first shift back at work after a run of hospital admissions. Since I came out have been nebbing 6 hourly and on 30mg of prednislone no dropping very slowely! I been feeling better than ever! anyway today at work I starting feeling a bit rubbish so took my nebs twice (9 hours shift) and I was coughing more and general asthma symtoms returned. My peak flow had dropped from 450 this morning to 320 this evening. So I have come to the conculsion that something at work is making my asthma worse. Work dont have any irritants around me or animals so took those off. Not effected by pollon (but have IgE) so I think it could be hte humidity we dont have air con just one fan between a the main desk and back office so still very stuffy and dont know where to go from here I dont wnat to be forced out of work and cant afford more time off!
