Ear canal swollen and same ear and eye on left side bumps all over and itchiness. Could there be something in ear or just allergic reaction.?

Allergic reaction. The itchy bumps imply an allergic reaction and should respond to some over the counter cortisone cream, but swelling of the ear canal usually means an outer ear infection (such as "swimmer's ear") and usually ear drops would be prescribed. Occasionally white vinegar or hydrogen peroxide can be used for mild swimmer's ear.
