I am looking for ideas for 16mth old with gas and pain possible lactose intolerance waiting for diagnosis? - gas pain more condition_symptoms

My son was diagnosed last month with the virus and constipation, and pain had all the time. I finally heard someone, and start to test, and I took his milk, but always seems to have pain. He wakes up at night in 30 minutes to an hour without interruption. The only way to make him happy to go, or take a walk. Whenever I am in my hand, and I'm tired of fear, until you start walking again.
I quickly lose my mind. Every idea, at least help to night? I've been in clinics / hospitals / and finally, now see a pediatrician finally beginning tests to see what happens. He feels the wind all day and night, because he was so young, I do not know what I can give. (I have water and Ovolo flu before it), Tylenol and Advil, nor any ideas for me?
