Hi can anyone give me advice. Just been for these tests and lung function was not too bad but she said the test for (is it nitrous oxide?) inflammation came back at 98 when anything over 25 is abnormal. They are going to change me from symbicort to seratide but wont get it till later this week. My lungs are really sore, and to me this looks like a huge amount off ""normal"" but at the time in the hospital I didn't really have time to think about questions. Does anyone have any idea how long it will take to feel better? Will I feel better? Had to go back on prednisilone this morning at peak flow 230 but it came back a wee while later after multi dosing with ventolin and spacer. Also have no symbicort at docs they said they cant get it the now and the doc wont prescribe the seratide till she gets the letter from the consultant.
