I had the lamb. Done on L4 L5 in 1996, doc told me in 2 years I'd probably have to have it fussed, as I still wanted to work and be active. Well I do back stretches every morning, every now and then I do something I shouldn't and it hurts for a couple of weeks. I fell on the dam ice here last winter, and was missed up for 2 months, if it wasn't for the C19 I'd have gone to the ER, but didn't, still stretches and made my self walk, doing good so far this winter. Wishing you Luck!
