Sounds obvious, have you any strong painkillers? I have had 2 episodes now of disc prolapses, and I take Solpadol with Dicloflex for usually the first 2-3 weeks, just so I can move around. I then switch to over the counter ibupfofen when needed.
I am 9 months on from my last disc slip, and have found swimming a massive help. I usually swim around 4-5 miles a week, couldn't quite 'get' pilates but know I should give it another go.
Like someone else has said, forget doing anything non-essential, housework is a no-no imo. Another obvious one - absolutely no lifting, and when you are in your recovery phase, still keep lifting to a minimum. I now shop with dd's umbrella buggy and use it as a trolley so I no longer carry any shopping. Looks weird, but I'm past caring! Oh, and forget gardening, I find even 'gentle' gardening causes considerable pain, so I simply don't garden, it's not worth it.
Hope you feel better soon, you have my sympathies! Try and keep positive - it's very, very easy to get low, talking to close friends helps, I had no idea just how common back problems were.
