I had a sciatica episode about 9 weeks ago during a hiking trip. I have herniated discs between L3 and L5 which have resulted in loss of muscle strength in my left leg (especially the quadricep, vastus lateralis) and loss of patellar reflex. Two neuro-surgeons and a PT have told me that surgery is necessary. However, I m going to a osteo-therapist and experiencing some gains, but still have significant loss of strength and reflexes. Is surgery necessary? If so, how long should I try a conservative treatment before getting the surgery (my doctor recommends a discectomy)? Thanks for your advice, Harold
