For the last 10 weeks I have had a constant feeling of tight chest, sometimes wheezing. I have tested my oxygen levels and they're fine. It's uncomfortable and is getting me down. I try to cough up what feels like phlegm but nothing comes up. There is nothing there to clear.
Covid 19 test - negative.
Antibiotics just in case test was an inaccurate result.
Antihistamines and nasal sprays in case it was hayfever.
It's every day. I don't know what else to do. I'm 42 and the GP has said it's too late on life to all of a sudden have asthma.
