I think because you have nerves compressed at L4 to S1 they will probably suggest an epidural at first to determine if something minimally invasive will help with your pain....If that does not help, a laminectomy will probably be offered. I think because the foraminal and recess nerves are involved they need to be decompressed, especially since it is severe. Notice the key word in this post though is "think." I am not a doctor...just know you have some of the same problems as me..and I went for the laminectomy...
