Just a warning. If the ear cleaning at home doesn’t work, see a doctor. I had a full sensation in my ear too, and my ears were actually squeaky clean – the problem was pseudotumor cerebri (too much fluid around the brain). Could have been something even more serious.
Rule 34: it’s not just for the internet anymore.
I once went deaf for some time in my left ear. On examination, a doctor found that there was a big lump of earwax up against the eardrum, preventing it from doing its thing. Money was very tight, at that point, so I didn’t feel I could afford to pay the doctor the $80 he wanted to clean it out; so I resorted to all sorts of do-it-yourself attempts, using various chemicals. I started, of course, by using Debrox, which is a product made specifically for this purpose; but it didn’t seem to be able to budge this blockage at all. I ended up trying all sorts of other various oils and solvents that I had on hand, the vast majority of which are probably generally a bad idea to use this way. What finally seemed to do the trick was a chemical that is supposed to be used for degreasing car engines. I can’t say for sure that this did it by itself, or whether it only worked because previous chemicals had sufficiently loosened the wax to the point that whatever I tried next was going to get it out.
The best advice that I would offer is to make regular proper use of something like Debrox, to keep the wax from accumulating to the point that more drastic measures will be needed to get it out.
Also, look into a device called the Ototek Loop, for physically scraping out wax that isn’t in too deep to be beyond its reach.
And as others have already said, stay away from “ear candling”. It is a potentially dangerous, and otherwise worthless scam. There is no realistic possibility of any benefit from it, and a significant danger of harm.
I will occasionally make my own version of that, from a paperclip. Straighten it out on one end, crimp the loop on the other end, and go to town (CAREFULLY!).
How would olive oil help? It’s just another lipid, not a solvent of any kind.
Or a bobby pin. No modifications needed. 
oils are solvents for fatty/greasy/waxy substances on an all depends basis.
Medical advice is best suited to IMHO.

Speak for yourself, I like the tingly bubbles, and the ‘swirlies’ I get.

Squeeky clean isn’t a term I thought I would hear about ears 
All those so-called earwax softeners don’t do squat for me. As I am evidently one of the world’s most prolific producers of earwax, I’ve decided that it’s a lot less aggravation to just go into the doc about once every four months and get the ears hosed out. Takes about 10 minutes, and except for the $15 copay, costs nothing because of insurance.
I use a 1:1:2 mixture of vinegar water & peroxide. See this thread to see how effective it is.
The most important part is to warm the mixture up to body temperature.
No comment necessary.
Sort of, well actually pretty gross: I once had such a dense build up of wax that debrox only made it worse. It only desolved the top layer, but trapped the rest, so I was stuck with a huge piece of wax AND a build up fluid in my ear. It was so bad it hurt and I couldn’t hear. It took forever for the doctor to flush it out. 
I ended up soaked, too. The next time I had it done, I brought my raincoat. Seriously. 
(Yeah, I’ve got waxy ears. Ugh! Fortunately I haven’t had to have them flushed in ages)
Here is a take on the importance of cleaning out ears by Johnny Earwax and Principal Schwinger and the crew of The Adventures of Pete and Pete.
Forget hydrogen peroxide. According to my GP’s advice and my own personal experience the best solution to wax buildup is the liquid stool softener Colace or one of the generic versions thereof (i.e., docusate sodium). Just drip into the offending ear and wait a few minutes. Then fill your irrigation syringe with warm water and have at it. Unlike HP the Colace will soften hard wax. If you have particularly problematic ears a drop in each one before bed will keep plugs from forming in the first place.
I’ve had to have my ears flushed a couple of times. Nowadays I let warm shower water spray into my ears during my shower every day, and use a Q tip to clean them out. This takes care of most of the wax. Occasionally I have to use a bobby pin to remove the wax, either with or without using a commercial wax softening preparation. I’ve also put a little astringent on a Q tip and used that to help get wax out. My doctor thinks that my outer ear canals are quite clean.
I was just stopping in to recommend this. It’s what I use on my patients in the ER.
I get my ears cleaned out every year as part of my annual check-in. “Audio enema” – heh! It’s true – when the big clump finally gives up its toehold it feels great.
I have one of those on my desk right now. And I thought I was the only one…
I started using it when I realized that Q-tips generally just push everything further up in.
