Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Your description says that you have an acute respiratory infection and hence the elevated white cell count. It is indicative of a bacterial cause and mycoplasma
is one of the usual agents to cause such lung infection
is unlikely due to mycoplasma.
The ear pain is due to congested eustachean tube occluding the tube with resultant hearing loss
Do you have any other neuro symptom like headache, vomitting, weakness in a particular area etc? A
Do you have fever, cough?
CT scan of the head may show the ear affection in greater detail.
Did your Xray (if done) shows any pneumonia
or infection in the lungs?
Common respiratory antibiotics, decongestants, steam inhalation may help the cause.
Any sputum produced may be sent for microscopy and culture.
Hope I have answered all your questions. I would be glad to answer any further queries.
Please ask for any clarifications before closing and rating this answer.
Thank you and Good luck!
