As a young person I had a blockage worsened by water trapped by the blockage. My uncle (an Ear Eye Nose specialist) had my mom pour some hydrogen peroxide into the affected ear. A lot of bubbling and problem resolved.

If your eardrum doesn't contain a tube or have a hole in it, these
self-care measures may help you remove excess earwax that's blocking
your ear canal:
Soften the wax. Use an eyedropper to apply a few drops of baby oil,
mineral oil, glycerin or hydrogen peroxide in your ear canal.
Use warm water. After a day or two, when the wax is softened, use a
rubber-bulb syringe to gently squirt warm water into your ear canal.
Tilt your head and pull your outer ear up and back to straighten your
ear canal. When finished irrigating, tip your head to the side to let
the water drain out. Dry your ear canal. When finished, gently dry
your outer ear with a towel or hand-held dryer. You may need to repeat
this wax-softening and irrigation procedure a few times before the
excess earwax falls out. However, the softening agents may only loosen
the outer layer of the wax and cause it to lodge deeper in the ear
canal or against the eardrum. If your symptoms don't improve after a
few treatments, see your doctor.
Earwax removal kits available in stores also can be effective at
removing wax buildup. Ask your doctor for advice on how to properly
select and use alternative earwax-removal methods.
Don't try to dig it out
Never attempt to dig out excessive or hardened earwax with available
items, such as a paper clip, a cotton swab or a hairpin. You may push
the wax farther into your ear and cause serious damage to the lining
of your ear canal or eardrum.
