Lactose intolerance?

Lat night at supper time I drank 30cc of skim milk.  All night I felt like I had someone sitting on my upper chest and like I had to burp but couldn't.  Is that the gas or the milk?  It started after the milk.  Anyone else have This?  MAybe I do need to burp but I just cant seem to!

I have the same thing. I have to drink really slow and it has to be super cold ( and cant just drink it allone)  .   they say most patience either have a start of that or gets worse. Hugs
