Gas bubbles that won't go away?

So my boyfriend, ever since I've known him has had these painful, cramp-like gas bubbles in his sides. These gas bubbles happen almost everyday.

Now, my boyfriend says the doctor told him to take laxatives.

My questions:
1: Will that work?

2: Why is this happening?

3:How can we temporarily lessen the pain while the laxatives do their magic?

Please help, I hate seeing him in pain.
