(I feel the need to say that I'm not a medical professional, so treat this all as anecdotal)
Dairy hit me hard a while back as well. It was a similar situation to yours,
@wildr0se2. I was bloated horribly. I could literally feel my bloated intestines by rubbing my torso. It was painful and nothing seemed to help. A doctor thought I had symptoms of something worse so I went through a battery of tests, all of which turned out normal. After that, he told me to "cut dairy." I did and all of my symptoms vanished within a week. It felt miraculous. I have avoided dairy since and the nastiness hasn't returned. I know dairy was an issue because I can get some semblance of the same symptoms if I inadvertently consume dairy (which sadly happens now and again). So I became dairy free against my will, but it seems to have had other benefits. I keep reading that human beings aren't really supposed to consume dairy as adults, but we just keep on consuming it out of habit and taste.
After all of this time, no doctor has recommended that I get tested for lactose intolerance. I've never been tested. I tell them my story and they say that's all they need to hear. A few have suggested that if I wanted to be absolutely sure, I could go back to my old diet for a few weeks and see if the symptoms return. I think I know enough from my occasional accidental incidents, so I haven't tried it. I don't want to even chance experiencing that again.
It's pretty easy to avoid dairy once one gets used to it, but it's a personal choice. It has worked out well for me.
