What will happen to someone who is lactose intolerant and drinks milk?

Am i lactose intolerant? Would i know? Please help?

• SO since tuesday i dont know if im becoming lactose intolerant or not. For like 5 days I ate nothing but fast food and greasy and crap food and had nothing but beer, energy drinks and pop, absolutly no water. Then tuesday night i had a burrito with cheesy sauce and my stomach didnt hurt but it felt like i had pressure and gas build up so when i peed it kind of hurt my bladder. Later tuesday night i was just farting on the way home. No smell or anything. Wednesday i felt better but still a little sour stomach...Thursday little sour stomach but not bad. Had pizza no stomach ache or gas or poop or anything from it. Then friday i woke up feeling fine then after moving around i felt naused for a while and began to have a bad headache like i was hung over. I ate and it seemed to go away. Then I had a cheeseburgar later on and sour stomach was still there but just sour. I think i may be freaking myself out. I had a pint of milk before work this morning to see if soemthing would happen and nothing happend until like 2 hours later where there was a little cramp pain for like 30 seconds but that may be just from my stomach hurting last couple days. Do i prolly just have a stomach bug because my diet was so bad for a week? Like i have no horrible stomach ache or anything after eating dairy....

• Answer:

  i don't think so, i mean if you consume milk products you will feel it right away, your stomach will extend and get bloated and sometimes you will get the shits, you will feel it in your tummy and nauseas too! there is also delayed allergies but i think you might just be eating too many foods with grease and it's bothering your stomach.
