Welcome in H.C.M.
I have gone through your query and after careful analysis of symptoms and their co-relation with possible pathological process which may be there, I hope that you are having severe acute upper respiratory tract
infection involving your nose and sinuses and extending back to throat and reaching the ear via eustachian tube.
Since you are feeling air hunger therefore some allergic involvement is also suspected.
For confirmation and treatment point of view you are advice for-
1- Culture and sensitivity of throat swab.
2- Sputum for AFB & Gram's staining.
3- X-ray chest and paranasal sinuses
After this a thorough examination and clinical co-relation of finding with investigations report will disclose the real facts of pathological process going on and that may be accordingly managed.
