If you've already been treated for orchitis by antibiotics, what other treatment is there available?

Depends: Orchitis typically refers to infection of the testicle and antibiotics are used to treat such infections. Sometimes a prolonged course of antibiotics (2-4 weeks) is needed to clear a serious infection. Orchialgia or testicular pain may persist after treatment of orchitis and is treated with Ibuprofen and tight fitting underwear or jock strap. See your doctor if you aren't feeling better.
