Hi there, I have a Grade 1 degenerative spondylolisthesis of L5/S1 and another one on L4/5 with pseudo disc bulging and bilateral foraminal stenosis causing partial impingement of L4 nerve root with back pain and pain going down my left leg. What is the best treatment for it? is an operation necessary? Thanks, mai
Decision of operation will depend on canal diameter, severity of symptoms and response to medications, any euro deficit. Continue physiotherapy, avoid bending forward and lifting heavy weight.  Take tab regain and analgesics SOS. Hope my answer will help you. Take care. Don't forget to rate me.
