Anyone had steroid injections into the lumbar area? Relief? How long?

Recently I had X-rays and MRI of the lower back after about a very severe pain for weeks. The diagnosis was osteoarthritis and moderate to severe degeneration of L4, L5 and S1. I can't control the pain somewhat with medications but do not like taking too much of these. My orthopedist has suggested I try steroid injections which may give relief for up to 6 months, but if the relief turns out to be short-term it is not a good option. Has anyone had the steroid injections into the lumbar area? If so, what were the results and how long did the relief last? I am 78 years old and have been very active all my life, and maybe this is the problem. The only other option suggest it was Fusion but I had rather stay away from that as long as I can.
