If my child gets a bad stomached when he drinks milk, does this mean he is lactose intolerant, is there a test for this?

Yes. There are specific tests for lactose intolerance (cho breath test, for example). Another way to test whether your child is lactose intolerant is to treat your child with lactase (the enzyme that digests lactose) regularly for several days up to a couple of weeks. If it helps, you have found a solution.
Yes. A breath sample can be tested for the presence of hydrogen. To obtain the sample, you will be asked to blow up a balloon-type bag. Normally, very little hydrogen is detected in the breath. You will then be given a lactose solution to drink. Breath samples are collected every 15 minutes for 2 hours to detect any increase in hydrogen in the breath as the solution is digested.

How does it feel to be lactose intolerant hi I have been drinking lots of milk latley and afterwards I get the worst stomach aches do you think that means I could be lactose intolerant?

Lactose. Lactose intolerance is the lack of an intestinal enzyme called lactase and is the inability to digest lactose - the sugar found in milk and other dairy products. Babies are born with the lactase enzyme and most lactose intolerance does not occur until age 3 or older if at all. As people age, they can lose the lactase enzyme. Symptoms can be bloating, cramps, diarrhea, nausea and poor growth in children. Some races such as asians and african americans are more susceptable to lactose intolerance than caucasians. A pretty good way to tell whether you are lactose intolerant is to stop eating dairy and see if your symptoms improve. Then, restart eating dairy and see if they return. If you enjoy milk and other dairy, you can try using "lactaid" products that already have the lactose component broken down or there are lactase supplements you can take prior to eating dairy.
Possibly. But lactose intolerant people not only have stomach pain after eating dairy products, they also experience severe diarrhea. If you have a feeling that you might be lactose intolerant please see a doctor for an official diagnosis and possible guidelines for treatment.

What OTC med can I take to get rid of stomach cramping from drinking milk? (lactose intolerant) using heating pad on my stomach but pain is still bad

Not much. Lactaid pills need to be taken with the first sip/bite of the milk product otherwise the GI side effects are already set in motion and you will simply need to ride it out.
