I am suffering itch inner ear and throat. I rubbed my ear I have pain in ear what will I do

If you're having ear pain, I would suggest you visit the doctor. You could have an ear infection.

Go to a clinic or doctor.
It's OK to put in a little peroxide to clean it, and then something like baby oil or olive oil to soothe it.
Your eustacean (sp?) tube may be clogged with mucous, or collapsed, and not draining properly into your throat as it normally should, or there's a pimple or small cyst with pus draining or not draining. Mine was clogged and hurting for years. After I had a molar below that ear removed it immediately went away, so I am sure it was related (and no doctor correctly diagnosed it).
But I know someone who had cellulitis in his ear and that's a bacterial infection and can be serious. So go!
