I had a bit of an exacerbation this afternoon whilst using wood restorer. I have fairly recently been put on the SMART regime and so took a dose of Symbicort then another 5 minutes later. The coughing and wheezing seems to have gone and my peak flow is not much lower than normal but I still feel quite short of breath and very tight from my throat right down into my lungs. This seems to happen to me more and more of late. Does it happen to anyone else?
