Hello, I went through your query, since you pain only when bending,, may be medical management is just enough for you, treatment includes combination of the following: Bracing to immobilize the spine for a short period (e.g. four months) to allow the pars defect to Heal,,,, Pain medications and/or anti-inflammatory medication, as neededStretching, beginning with gentle hamstring stretching and progressing with additional stretches over time,, exercise that is controlled and builds gradually over time(your doctor prescribe you that) , if your symptoms include neurological components then surgical approach may be needed, please consult a neurosurgeon or orthopedician.
