Just finished my second course of steroids in a month and still on Seretide 500 twice a day. Symptoms improved dramatically during this course of preds, my pf increased to 430, the best for months. Now that they are finished it has dropped back to 280 - 300. My GP said I was not reacting normally to asthma treatment and sent me for a chest xray that I had on friday. I have to go back to gp for results next week but I am wondering what he might suggest now. I have at last returned to work this week and it has been great to be back instead of feeling miserable at home but I have been completely exhausted every night. I was really hoping that the preds would finally knock this on the head but it just feels that my lungs are never going to be normal again.
