Hi. All your symptoms sound like they are due to impacted
ear wax.
I am guessing that your attempts to unblock your ear may have involved inserting an earbud or something similar into your ears. Excessive manipulation of the
ear canal can trigger a nerve called as the
vagus nerve ( supplies the back wall of the ear canal) and that can cause you to feel dizzy and can also precipitate
diarrhoea (through a parasympathetic response). Pouring water into the ear will only make the wax swell since wax absorbs some of the water and this would impact it further into the ear canal.
I would strongly recommend that you have your ears looked at by an
ENT specialist and have the wax removed under microscopy. There is a small possibility that this is not impacted ear wax if the ear clogging started after a
cold or blocked nose. In which case it may be a eustachian tube blockage for which the treatment is different. You ENT specialist will be in a position to identify the cause accurately and treat you for the condition.
Here is some trivia on ear wax that you may find useful:
Ear wax is produced by glands present in the outer part of the ear canal which is close to the ear pinna. The skin in the outer ear canal grows outwards at the speed of 1 to 3 mm per day. Wax that is produced is expelled out on its own along with the growing skin. Therefore there is no need to try and remove the wax from within the ear canal.
By inserting an ear bud the wax is pushed inside the canal into a narrower bony region from where the skin is tightly adherent to the bone and hence does not grow outwards. Hence the wax stays there, dries up and gets impacted. This can cause decreased hearing and also pain if it gets infected.
The best way to remove ear wax is by cleaning the ear canal superficially by the edge of a towel or handkerchief after a hot water bath. For those with large amounts of sticky wax may need to put drops that help dissolve wax.
Remember, ear wax is protective. It prevents entry of dirt, reduces infection and even prevents insects from entering into the ears.
