My case isn't serious. Yes, I've treated a lot of my own medical problems without consulting a doctor.
Not that I have problems paying, with or without insurance, but I imagine they would do an X-ray on my ear and then prescribe some medication (assuming its an infection). Way more than $10.
Sounds like Otitis media with effusion (if you have any drainage). The doctor will probably look in your ear with an otoscope to look at your tymps. If there's fluid, they will bulge a little outward because of the pressure. The fluid is not CSF, just fluid buildup from probable eustachian tube dysfunction or middle ear secretions (e.g. goblet cell hypersecretion). It could be CSF if you've had a skull fracture, but you didn't say anything about that. You are experiencing this probably because of an upper respiratory infection (usual cause) or it could be allergies, pressure differentials, bacterial infection, or general eustachian tube dysfunction. The physician will typically NOT take an xray of your ear for this, unless you've been exhibiting chronic symptoms of prebycusis, and in that case, you'd have been to an ENT, then to an audiologist, and back to an ENT for the xrays. The easiest test to run to determine if there is fluid in your ME cavity is a tympanogram, which a lot of offices have. (general diagnostic tool).
If you want to save yourself time and money, when you start to feel that dull "echo" as if an ear infection is coming on, start taking an antihistamine (or other allergy medication) that helps clear your head if/when your get allergies. You could also take guafenisen, an expectorant alternative to antibiotics. If you still feel stopped up after a few days, then go to the doctor.
The bony ridge you describe sounds like the helix of the ear.
I realize this post is a little outdated, and your ear infection has probably cleared by now, but you could use it as advice.
And I'm not a doctor. Most people that post here are not doctors - they are premeds or med students. Occasionally you'll run into a resident. I'm a speech-language pathologist with an audiology background so take my advice knowing I'm not a physician, but have audiology experience.
