Exercise with herniated lower back discs?

Aquafly

I know I need to lose weight.. a lot of weight.
I am suffering right now with the pain of 3 bulging discs in my lower back. I saw a dr. yesterday and will see another tomorrow.

If anyone else suffers from herniated lower back discs, what exercises do you do?

I've gone to physical therapy before and was shown stretching exercises I do every day, but this flare up is the worst ever.

It's a shame it took this horrible pain to finally make me totally stick with losing weight. I wouldn't want this pain to ever come back, and if weight loss can prevent it, that's what I'll do.

Can anyone give me advice on what to do as far at exercise when I'm suffering from painful herniated discs?
