Lactose Intolerance/pain in back on right side?

[Nessicle]

Whenever I have a glass of milk before bedtime I wake with pain on the right side in my back and its really hurting. Anyone else have this? I can barely move its rubbish

I have lactose intolerance, I was diagnosed years ago. Can't say I've ever had that problem. If I have too much lactose I just get really bloated and have terrible gas pains but it's usually all gone in the morning. Could your pain be bowel related?
