My ear has been clogged for two days and i put hydrogen peroxide inside yesterday to unclog it but it didn't do anything at all. it doesn't hurt.

Be seen: Most likely, as you suspected, you have ear wax plugging your ear canal. H2o2 has been used by folks to dissolve it but that is a harsh chemical that can damage skin, especially if used full strength. Safer ways exist to clean out an ear. Also, other things can cause that problem that might be in a different part of the ear, so the best approach is to have someone who knows what they are doing loo.
