Truth about pain?

My mom is upset that I'll be getting an epidural. But I don't want to feel anything. 
I mean can handle period cramps and Braxton hicks. However what hurts more than that is drinking milk! I'm 100% lactose intolerant and have the WORST cramps when I drink milk. To the point where I can almost pass out from the painful stomach cramps. 
What do labor pains REALLY feel like. If they are anything like period cramps or BH I think I'll be good, right?
