Combined approach. Manipulation can be helpful, but I prefer a multifaceted approach incorporating non steroidal or steroidal antiimflammants, muscle relaxants, and analgesics if indicated. Massage can be helpful. If the patient fails to respond to the above within one to two weeks, then certainly appropiate diagnostics should be pursued, ie x rays followed by MRI of the lumbar region to determine the exact cause.
Osteopathic therapy. Osteopathic manipulation is a great way to help with your sciatic pain without medication.
