Ringing blocked ears?

I woke up 5 hours ago and my right ear had a ringing bell noise and also seems blocked, after taking a further nap the problem consists and there is no pain,, very similar in having water in it, I havnt been swimming also no water has entered my ear canal. would anyone know what this is?

Wax buildup! 

Meant to out a question mark there not yelling.

Possible explanations are:

Excess wax

Fluid in the middle ear (if you've had a cold lately)

Sudden hearing loss (more common in diabetics and patients 50 years and older)

My advice is to see an ENT physician.
