I am suffering from three months from this. Sometimes I feel that there is no problem at all.
I feel like i dont have any lung problem.
But then sometimes i feel some breathing problem for like 1-2 hours. It feels like something in my trachea below vocal cord. When i cough very little phlegm come out. It happens in evening and morning. I sleep pretty well. No breathing issues once slept. I dont know whats the problem. I have allergy that too from dust mites. But when i sleep i feel nothing. Also some headache from 3-4 weeks i am sure not related to sinus.
My Chest x-ray shows nothing. Suffering on and off for 3 months.
Did anyone had symptoms like me ? Even oxygen saturation level is always normal(around 90). I dont feel breathless when walking or even running for a while. I had B12 like 230 pg/ml which is normal but less i am taking supplements. Plus thyroid also normal. But my allergist suspects something metabolic.
