Asthma can also be due to exposure to certain irritants, known as Irritant Induced Asthma (IIA), especially if you are exposed to a high dose of that irritant (typically at work, even though you can get it at home). Here, usually there is no family history of asthma, or associated allergic rhinitis/sinusitis or eczema.
There is also another variant of asthma called Reactive Airway Dysfunction Syndrome (RADS), which is similar to IIA in that the airways respond to a high dose of an irritant. Once you are removed from that irritant, symptoms can go away.
The outer ear consists of the pinna and the ear canal . The infection of the outer ear is called Otitis Externa and can present as sores of the pinna and/or sores in the ear canal. This is treated with ear drops.
The middle ear consists of the inner part of the ear drum, 3 small bones, Eustachian tubes, round window and oval window. The infection of these structures is called Otitis Media. Usually, it presents as a discharge (pus) through the ear .The gold standard treatment for Otitis Media is antibiotics.
Most likely, this time you have otitis media.
