Doctor told me to do physical therapy and if pain persists to call him to get an order to see a Spine dr. The problem is that I am in constant pain, my left side is totally numbed, i feel tingling that goes to my hands, and arm left side and neck. Mild degenerative disc disease at L4-L5 AND L5-S1.The disc bulge  <response>: Hi you have L4L5 disc lesion with Left nerve root compression as per your MRI report. For your left side numbness if it is totally form head to toe than there were other reason of it. Your neck arm hand numbness or tingling had no relation with your L4L5 problem. There were chances that your physical exercise had cause it. For your Lumber problem you have to consult spine surgeon. Have a nice day.
