 [ Symptoms ] i have been having some trouble breathing through my nose [ Disease ] it looks like either you have thick mucous plugging your sinuses leading to sinus infections or sinusitis and as the sinuses drain through nose you have blocked nose also the back of nose and the ear are also connected via eustachian tube and the tube can also get blocked due to mucous this seems to be the most probable cause other can be nasal and sinus polyps so a pns view x ray and cbct test will help in confirmation of the cause as of now steroid nasal drops decongestants saline nasal irrigation and steam inhalation can help hope this helps regards
