O'Malley:
My advice, consult an ENT to be safe, particularly an ENT with dive medicine knowledge.
Hi... just thought I would add my 2 cents... (I'm an ENT doc)..
There are a lot of misconceptions about ear problems with diving, and it's important to keep things straight. The problem is that people tend to view any pain or hearing loss as being the same thing, which is not always true.
To summarize- there are three places where you can have ear trouble during diving, and they all have different clinical courses, prognosis and treatment. If you have problem following along without a diagram, there is one on my othe Web site,

1) Outer ear problems: Water from the ocean can get stuck in the external ear canal, especially if there is a good plug of wax. Rarely, a tight wax plug can cause a squeeze in the outer ear, but this isn't very common. Also, you can get an irritation of the skin of the ear canal (swimmer's ear). People who spend a lot of time in cold water can get bony growths in their ear canals ("surfer's ear"), these can also trap wax and water if they get big enough.
Treatment (if it doesn't get better by itself) is careful office cleaning by an ENT doc with a microscope, possibly followed by medicated ear drops. If there is swimmer's ear, it is good to keep the ear dry. This is not always possible with multiple days of diving, but using a hair dryer or a 50:50 mix of rubbing alcohol and white vinegar may help prevent recurrence. The bony growths occasionally require surgery if they get too big. Q-tips can cause injury or further impaction of earwax against the drum- not a great idea.
2) Middle ear problems: The middle ear is the space behind the eardrum. Barotrauma (pressure injury) can be caused, as you all probably know, by not allowing for the Eustachian tube (the natural drainage pathway of the ear) to do it's thing and equalize the pressure from the airtight middle ear with ambient pressure. This usually happens when you descend too fast without equalizing (remember, equalize early and often), or when you dive with a cold (causing swelling of the Eustachian tube). Generally, this results in a clear fluid with or without blood in the space behind the eardrum. This does NOT lead to middle ear infections (pus behind the eardrum, as commonly seen in young children).
Treatment- Unblock the Eustachian tube by valsalva maneuvers (pinching the nose and blowing) or Toynbee maneuvers (pinching the nose and swallowing, or other maneuvers with the jaw to ventilate the ear. Medical therapy (decongestants, anti-inflammmatory agents like motrin, or steroids) can help to some degree. Very rarely, it will be necessary to make a hole in the eardrum. This usually is necessary when a "vapor lock" sets in and the fluid lasts more than a few weeks. I have only had to do this once or twice in the last 10 years.
3) Inner ear problems: The inner ear is the space deep in the ear bone where the cochlea sits. The cochlea is the organ of hearing (like the retina in the eye) that converts sound waves into nerve signals.
Diving related inner ear problems are very rare, but have the potential to cause permanent hearing loss. There are two types- inner ear decompression illness (a type of DCI in which the bubbles form in the inner ear), and inner ear barotrauma (leakage of inner ear fluids through a fistula). These require immediate attention, and in the case of a leaking fistula, may require emergency surgery.
Bottom line: The vast majority of pain after diving goes away in a short time, but without an examination, you may not be able to tell whether the problem is in the outer or middle ear. Furthermore, the ear is unfamiliar territory for many general doctors. I don't say this to get more business..! I very much respect the pediatricians that I work with. But I have realized over the years that it can be very difficult to accurately diagnose ear problems without a lot of experience and the right equipment!
