Back pain keeps coming back when the symptom settles down because you may have rested and temporarly aleviated the symptoms but the underlying condition that is causing the movement problem has not been corrected.  Many people feel better once inflammation drops, then return to the same lifting, driving, sleeping, or sitting habits with the same spinal dysfunction still in place.  That is why one-off relief care often fades, especially for working adults in Garland, Sachse, and Wylie who keep putting stress on the same area.  Pain that is masked with pain killers or ointments returns; pain that is corrected resolves.  You are human and nothing is for ever, meaning eventually you my suffer a new injury (new episode) as you get older and stop exercising but a new episode may take months or even years if the initial injury was addressed and healed properly.  Dr. Ruy Amador, DC recommends that adults between the ages of 30 to 60 years of age get screened and adjusted about every 2 to 3 months in general for wellness (preventive care) and not waiting for pain or disfunction to be the driving factor for seeking chiropractic care.  However, each person is different and has different job stressors and medical conditions so consult your Chiropractor for your individual proper recommendations.
