If you have never had chronic low back pain then there is no way to describe it. You get to the point that even surgery with mixed odds is a risk worth taking. The decision is not taken lightly by the ortho and certainly the patient. When a disk herniation gets bad there are really no conservative fixes available.
I only have stage one disk degeneration and osteo arthritis and the pain is unbearable on many days. I can not imagine the pain from a herniation. On top of the pain there are other problems with having severe inflammation going on around the nerve branches. When it gets to that stage you have two options, surgery or suicide.
In my case a spinal epidural steroid injection got rid of 95% of the pain so that I can devote a full hour a day to extension exercises and mountain biking to reduce some weight. To assist the disk material to start regenerating I am doing high dose amino acids. So far my finger nails are growing like mad so that is a good indicator.
I really hope it goes well for you and you get some relief. Keep us posted and have a goal set for what you really want to get back into or do afterwards. Frame of mind and attitude plays a very important role in recovery.
Best wishes!!!!!!!
