I've been switched from Symbicort to Fostair after a chest cold kicked off my asthma. I've been using Symbicort for many years and it has been life changing for me. Since moving to Fostair I have been feeling pretty unwell. I have back pain over shoulder blades; my chest feels hyper-inflated; I have no appetite; I feel nauseous; I have muscle cramps; my muscles hurt like I have flu; I have no energy; I feel anxious; I have palpitations; sore neck; thudding in my ears and headache and most of all my asthma is not controlled even with the recommended dose. I'm not a complainer and I always give things a good go but I'm thinking this isn't working for me. Has anyone else suffered on a Fostair switch?
