Not saying this is what you have but can hurt to try.
this is a likely cause (called a "wax impaction")... it's happened to me a half-dozen times and it feels almost exactly how you describe. Tends to happen out of nowhere.
Murine works for some, but hasn't for me. My best luck has come from hydrogen peroxide... lay on your side, drip it in till it's full and let it fizz in there for 10 minutes. afterwards you'll probably be able to pull out a crap-ton of now-soft earwax with Q-tips (obviously with gentleness and great patience as not to do any permanent damage). It usually takes me 3-4 days of doing this a couple times a day before it finally clears, but if you let it clear naturally it can take weeks.
