Does anyone else have adverse reactions when eating garlic?

In the past few years my body’s grown intolerant of garlic. It can be fresh, roasted, dried, etc. and though it tastes so good, it does bad things to my guts.

Last night I ate a glorious dinner that had garlic sauteed into the sauce but I picked out the pieces. I didn’t get the usual upset stomach or run to the potty but I did get a throbbing, radiating from bone pain in my lower back that wouldn’t let up until I ate several ibuprofin. Today the pain is gone, like it was never there. What the hell?
