Yes- joyjo
I have/had pain before my gallbladder removal on both sides .
The right side was a stabbing, pinching pain like a large blade through my belly to my back
Left side more a stabbing pinching but in one place.
Horrible bloating and daily loose bowels ( nice )
Long story short.
All tests showed nothing sinister but Diverticular Disease.
Been following Low FODMAP for a week (I;m a vegetarian, non smoker non drinker. Don't eat butter (yuk) , minimal cheddar (hurts) . Lactose free milk made no difference .
Have cut out completely : dairy,gluten,wheat, onions,garlic (and milk chocolate), orange juice, beans
Much improved.
I'm not bloaty. I'm not in pain,
It's tough, I'm only a week in and it's bloody hard. I chose to be vegetarian. I chose not to smoke or drink.
I didn't choose the pain or the horrific loo experience every day 
But, I'll get there.
Might be worth a try?
