L5 Herniated

Oct 2010 I was helping someone move filing cabinets.  Two days after the move I felt a lot of pain in my right butt and hamstring.  The pain never went past the knee however my mobility has been greatly hindered.  It almost felt like i pulled my hamstring muscles or glut.  The pain was probably a 9 out of 10.  5 months later on March 2011 The pain is like a 4 but I only feel it in the right buttox and sometimes in the right hip area.  The Ortopedic diagnosed me as a Herniated L5 disc pinching my nerve causing pain from results of MRI.  However I am confused.  Since the disc has shifted, is this permanent? What causes the disc to shift back in to place? I do a lot of jogging and pushups and situps.  Should I continue these activities or is there any specific excercises I should concentrate on?    Will I no longer be able to do something like this because of this condition?  I need some opinions on this.. I am a little confused on how this cures itself and if this is permanent.

Mild lower lumbar spondylosis.
At L5-S1, a broad central to right foraminal disk protrusion displacing the right traversing S1 nerve root with mild spinal canal stenosis and moderate right foraminal narrowing.
At L4-L5, mild spinal canal stenosis with moderate right foraminial narrowing and mild to moderate left foraminal narrowing.

Hi I am not a doctor just a patient.  Has you doctor advised you?  I had a similar problem with the disc pushing on my S1 nerve root.  For 8 months I was in pain, the doctor thought it was muscular and so he tried, rest, ice/heat, then physical therapy, trigger point injections, etc, before deciding on surgery.
I was very happy with the results of the surgery, it was laprooscopic
Good luck, I am sure others will join in
