The possible cause of back pain in your age group will be positional abnormalities in the first place.2. Other possible cause could be systemic disorders like inflammatory / infective cause of the spine.3. You need to try back exercise initially followed by the physiotherapy if symptoms persists further investigations might be needed.4.MRI is the best investigation of choice for evaluate the cause.  - see your GP and get the physiotherapy. Good luck. Hope I have answered your query,anything to ask do not hesitate to ask.http://doctor.ChatDoctor .com/doctors/ Chat Doctor.  </s>
