When I had my 3 months off with a herniated disc and back in permenant spasm (I have never had pain like it) I used a tens machine, it doesnt take the pain away completly but it makes it bearable enough to heal, also if you can do some 'core' muscles exercises like these

also one of those huge balls that they have in gyms, if you just sit on it and try to keep it from moving will help the muscles around your spine strengthen up.
Failing that, get someone else to do the work!
Hedgerow Pete told his doctor, 'I've got a bad back. 'The doctor said, 'It's old age.' Pete said, 'I want a second opinion. 'The doctor says, 'OK. you're ugly as well.'
Hedgerow Pete and Steve are talking one day when Bill says, "I finally went to see the doctor for the pain I've been having in my back."
"So, what happened?" Steve asks.
"Well, first he ran a series of tests," Pete explains. "Then he gave me some pills, told me to stay in bed for a week and sent me home. He also told me to sit down whenever I have to pee. Can you imagine that? A grown man having to sit to pee?"
"Did he say why he wants you to sit to pee?" Steve inquires.
"Well, with my bad back, he doesn't want me lifting anything heavy!" answers Pete.
