My ear developed a pimple deep down inside and my whole ear is swollen shut it sounds like i have water in my ear but today there is so much pain and?

Need drops Rx: It sounds like you need to have that ear looked at. A prescription for ear drops to help with the swelling, infection and pain. You may need a wick inserted for a few days to help the medicine get into the swollen ear canal.

See doctor : Don't wait any longer. You need to see a doctor about this and find out what is going on.

See a doctor today!: Please see a doctor today to find out what is going on and start appropriate treatment. An ear infection (which is what this appears to be) can rapidly become a very serious condition given the close proximity to the skull base and the brain!
