How long after finishing my treatment for chlamydia will the symptoms disappear?

Usually quickly. If you were treated for uncomplicated chlamydial cervicitis, then almost immediately. If you had greater symptoms, such as pain or possibly fever, then usually within 1-2 weeks depending on what treatment was prescribed, and the severity of the infection. A longer recovery may be caused by infection of the pelvic organs such as the fallopian tubes, which would cause greater symptoms.
