In March I started with a little cough...not covid. Since then it has become chronic. I have a stuffy nose and terrible mucus on my lungs. I am coughing, wheezing and have difficulty breathing worse at night and in mornings. I can cough up lots of thick mucus. It's so scary not being able to breathe. Been to GP many times. Had a chest x-ray (clear) and been prescribed strong antihistamines, nasal sprays and inhalers. GP says hayfever but I have never had hayfever before. Pollen levels low at the moment but I have been woken up again this morning with the terrible cough and breathlessness. My lungs are on fire. A few puffs of a blue inhaler has helped. I just want this, whatever it is to go away. It is severely impacting my life and making me very down. Could I have developed an allergy to something else?? Has the covid vaccine triggered something?
