Hi, new here. I’m seeking some ideas here.
I’ve been treated for asthma for over 20 years. I’ve had new inhalers recently but resorted to ones I’ve been taking for some time. In December I became unwell. My go gave me prednisone for a week. That did nothing. He diagnosed a virus (not covid). Still struggling with breathing over 3 months later. Some of my symptoms, breathless, dizzy, muggy, bad cough, high heart rate, lowish oxygen, chest pains and so on, have been relieved after six vit b12 shots but still struggling with chest discomfort and breathlessness. Chest x-ray clear. Now gp not sure it’s asthma. I have at last got an appt for a lung function test. What tests are they likely to do?
