I had disk related leg pain so bad a few years back that I could not stand for more than 10 minutes before having to sit or bend over forward. I commuted by foot then and I would have to stop 5 times on my way home. I was luck to connect with a great PT and with a lot of attention to core muscle building exercises was able to beat the pain without surgery or drugs. I still have back pain from time to time but nothing severe and no more of the horrible leg pain.
So don't rush into surgery real quick - and good luck.
